EVAL-LTC7063-AZ

150V Half-Bridge Driver with Floating Grounds and Adjustable Dead-Time

General Description

The EVAL-LTC7063-AZ evaluation circuit is a half-bridge driver that drives two N-channel MOSFETs. The PWM input control is 5V logic compatible and controls both gate outputs, with one output being the complement of the other. The eval kit has several unpopulated PCB pads to help facilitate the user in customizing the board for their application.
The LTC7063 driver has a powerful 0.8Ω pull-down and 1.5Ω pull-up MOSFET drivers driving two 150V N-channel MOSFETs. The gate drivers on the LTC7063 are capable of driving MOSFETs with different ground references; however, this eval kit has these ground references committed.
Design files for this circuit board are available.

Performance Summary (TA = 25°C)

PARAMETER	MIN	TYP	MAX	UNITS
Logic Input Supply (VIN-LOGIC)	6		14	V
Power Input Supply (VIN-POWER)	150	V
Maximum Output Current	10	A
PWM Control Frequency	2,000+	kHz
Maximum PWM Control Voltage	5.5	V

Quick Start Procedure

The EVAL-LTC7063-AZ can be evaluated without connecting any additional components or a load. However, the user may find adding two load resistors, as shown in Figure 1, provides a better means for evaluating. Alternatively, the user can configure their own application circuit. Test with a resistor divider as a load:

Connect two 100Ω power resistors to the SW node, as shown in Figure 1.
Apply VIN-POWER supply.
Apply VIN-LOGIC supply.
Apply a square-wave signal at the desired frequency to the PWM pin, as shown in Figure 1.
Ensure the JP1 jumper is set to “ENABLED”.
Monitor the BG, TG, and SW pins with a scope.
See Figure 2 for expected results with:
VIN-POWER = 40V
VIN-LOGIC = 10V
PWM input set at 5V peak at 1kHz
