• Load resistors capable of sinking up to 400mA (8.25Ω for ADPL16000A, 12.5Ω for ADPL16000B, and 30Ω for ADPL16000C)

Equipment Setup and Procedure

The EV kits are fully assembled and tested. Follow the steps to verify and test individual converter operation:
Caution: Do not turn on power supply until all connections are completed.

1. Disable the power supply and set the input power supply at a valid input voltage.
2. Connect the positive terminal and negative terminal of the power supply to the VIN pad and its adjacent PGND pad of the converter under evaluation.
3. Connect the positive terminal of the 400mA (max) load to the VOUT pad and the negative terminal to the nearest PGND pad of the corresponding converter.
4. Connect the DMM across the VOUT pad and the nearest PGND pad.
5. Verify that the shunts are not installed across pins on jumper JU101 for ADPL16000A, JU201 for ADPL16000B, and JU301 for ADPL16000C. See Table 1 for details.
6. Turn on the input power supply.
7. Verify that the DMMs display the expected terminal voltages with respect to GND.

Detailed Description

The ADPL16000A/ADPL16000B/ADPL16000C EV kits are designed to demonstrate the salient features of the ADPL16000A/ADPL16000B/ADPL16000C high-voltage, high- efficiency, synchronous step-down DC-DC converters. The EV kits consist of typical application circuits of three different converters. Each of these circuits is electrically isolated from each other and hosted on the same PCB. Each of these converters can be evaluated for their performance under different operating conditions by powering them from their respective input pins.

Enable/Undervoltage Lockout (EN/UVLO) Programming

The EV kits offer an adjustable input undervoltage-lockout level feature for the converters. For the ADPL16000A, when jumper JU101 is left open, the converter is enabled when the input voltage rises above 5V. To disable the ADPL16000A, install a shunt across pins 2-3 on jumper JU101. For the ADPL16000B, when jumper JU201 is left open, the converter is enabled when the input voltage rises above 7V. To disable the ADPL16000B, install a shunt across pins 2-3 on the jumper JU201. For the ADPL16000C, when jumper JU301 is left open, the converter is enabled when the input voltage rises above 15V. To disable the ADPL16000C, install a shunt across pins 2-3 on the jumper JU301. See Table 1 for jumper settings. Refer to the Setting the Input Undervoltage- Lockout Level section in the ADPL16000 data sheet for more details. If the EN/UVLO pin is driven from an external signal source, it is recommended that a minimum 1kΩ series resistance is placed between the signal source output and the EN/UVLO pin to reduce voltage ringing on the line.

Mode Selection

The ADPL16000A/ADPL16000B/ADPL16000C converters support PWM and PFM modes of operation. In the EV kits, leave the jumpers (JU102 for ADPL16000A, JU202 for ADPL16000B, and JU302 for ADPL16000C) open for operating the modules in PFM mode at light load. Install shunts across positions 1-2 to configure the modules in PWM mode. See Table 2 for jumper settings. Refer to the Mode Selection (MODE) section in the ADPL16000 data sheet for more details.

Adjusting Output Voltage

The ADPL16000C supports a 0.9V to (0.89 x VIN)V adjustable output voltage. Output Voltage in the ADPL16000C EV kit is preset to 12V. Output voltage can be programmed using the feedback-resistive divider (R304 and R305) from VOUT and GND. For programming the output to a different voltage, refer to the Adjusting the Output Voltage section in the ADPL16000 data sheet for more details.

Input Capacitor Selection

The input capacitors C106 for the ADPL16000A, C206 for the ADPL16000B, and C306 for the ADPL16000C, serve to reduce current peaks drawn from the input power supply and reduce switching frequency ripple at the input. Refer to the Input Capacitor section in the ADPL16000 data sheet to choose input capacitance. Input capacitor is chosen to be 1μF/100V for the ADPL16000A/ADPL16000B/ADPL16000C EV kits.

Output Capacitor Selection

X7R ceramic capacitors are preferred due to their stability over temperature in industrial applications. The required output capacitor (C109, C209) for the ADPL16000A and ADPL16000B is 22μF/6.3V. The required Output Capacitor (C309) for the ADPL16000C is 22μF/16V. Refer to the Output Capacitor section in the ADPL16000 data sheet for more details.

Hot Plug-In and Long Input Cables

The EV kits provide optional electrolytic capacitors 22μF/100V (C103 for the ADPL16000A, C203 for the ADPL16000B, and C303 for the ADPL16000C) to dampen input voltage peaks and oscillations that may arise during hot-plug-in and/or due to long input cables. These capacitors limit the peak voltage at the input of the DC-DC converters when the EV kits are powered directly from a precharged capacitive source or an industrial backplane PCB. Long input cables, between the input power source and the EV kit circuit, can cause input-voltage oscillations due to the inductance of the cables. The equivalent series resistance (ESR) of the electrolytic capacitor helps damp out the oscillations caused by long input cables.

Electromagnetic Interference (EMI)

Compliance to conducted emissions (CE) standards requires an EMI filter at the input of a switching power converter. The EMI filter attenuates high-frequency currents drawn by the switching power converter and limits the noise injected back into the input power source.
Use of EMI filter components as shown in the EV kit schematic results in lower conducted emissions, below CISPR32 Class B limits. Manufacturer part numbers of the EMI filter components are listed as optional BOM. The EV kits’ PCB layout are also designed to limit radiated emissions from switching nodes of the power converter, resulting in radiated emissions below CISPR32 Class B limits. Further, capacitors placed near the input of the board help in attenuating high-frequency noise.
