Power Device Delivers High Current In Small Form Factor

Expanding the PowIRstage family of devices, the 40A IR3553 integrates a synchronous buck gate driver, benchmark figure-of-merit control, and synchronous MOSFETs and Schottky diode into a 6 mm x 4 mm x 0.9 mm PQFN package. The device is fully PWM compatible with the company’s CHiL digital power control products, as well as most industry standard PWM controllers. Price for the IR3553 begins at 1.95 each/10,000.
