EVQ1923-RE-00A

EVQ1923-RE-00A is an evaluation board designed to demonstrate the MPQ1923, a high frequency half-bridge gate driver. The MPQ1923 has a 7A source current (ISOURCE) and 8A sink current (ISINK) at a 12V driver power supply voltage. The integrated bootstrap diode reduces the external component count. The device’s HS-FET and LS-FET drivers are controlled independently, and can be matched with a time delay (5ns). If the IC supply is insufficient, then UVLO protection on both the HS-FET and LS-FET force the outputs low. The MPQ1923 is designed for motor drivers and other power-control applications (e.g. telecommunication half-bridge power supplies, avionics DC/DC converters, two-switch forward converters, and active-clamp forward converters. The MPQ1923 is available in a small QFN-10 (4mmx4mm) or QFN-8 (4mmx4mm) package. The EVQ1923-RE-00A is configured as a buck converter. The INH and INL pins are independent signals. Choose complementary PWM signals and a proper dead time for INH and INL.

• Driver power supply voltage range (VDD) from 5V to 17V
• Input power supply voltage range (VIN) from 0V to 100V
