Smaller footprint and enhanced efficiency for 27A converters

Vishay has introduced the SiC714CD10 and SiC711CD10 synchronous buck regulators, capable of delivering continuous output current of 27A and 25A respectively, in the thermally-efficient 10mm x 10mm PowerPAK® MLF package

Both devices integrate the control MOSFET, synchronous MOSFET and driver circuit for a synchronous regulator, and connect directly to a PWM controller or ASIC. This topology minimises parasitic leakage inductance and achieves 3% better efficiency than a comparable discrete solution.

An external pin to control the low-side MOSFET permits pre-biased start-up, thereby avoiding undesirable sinking of current from a pre-charged output capacitor. In addition, break-before-make operation prevents shoot-through and minimises dead-time. Other features include Under-Voltage Lockout (UVLO) and turn-on/turn-off capability. Both devices are optimised for 12V-to-logic-voltage conversion.

 

FEATURES Input voltage range: 3.3V to 16V Switching frequency range: 100kHz to >1MHz Internal bootstrap diode SiC714CD10 optimised for 10% duty ratio SiC711CD10 optimised for 40% duty ratio
