General Description

The EVAL-LTC7066-AZ evaluation circuit is a half-bridge

driver that drives two N-channel MOSFETs. The two 5V

logic-compatible PWM inputs independently drive each of

the two N-channel gate outputs to each MOSFET. The

eval kit has several unpopulated PCB pads to help

facilitate the user in customizing the board for their

application.

The LTC7066 driver has a powerful 0.8Ωpull-down and

1.5Ωpull-up MOSFET drivers driving two 150V N-channel

MOSFETs. The gate drivers on the LTC7066 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.

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:

1. Connect two 100Ωpower resistors to the SW node, as shown in Figure 1.

2. Apply VIN-POWER supply.

3. Apply VIN-LOGIC supply.

4. Apply two 5V, 1kHz square-wave signals 180° apart with a 48% duty cycle, as shown below. Limiting the duty

cycle to 48% and staggering them 180° apart will ensure no shoot-through.

5. Monitor the BG, TG, and SW pins with a scope.

6. See Figure 2 for expected results with:

a. VIN-POWER = 40V

b. VIN-LOGIC = 10V
