Overview
Technology Licensed from International Rectifier APU3037 / APU3037A 8-PIN SYNCHRONOUS PWM CONTROLLER DESCRIPTION The APU3037 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications.
With the migration of today’s ASIC products requiring low supply voltages such as 1.
8V and lower, together with currents in excess of 3A, traditional linear regulators are simply too lossy to be used when input supply is 5V or even in some cases with 3.
3V input supply.
The APU3037 together with dual N-channel MOSFETs such as AP60T03, provide a low cost solution for such applications.
This device features an internal 200KHz oscillator (400KHz for "A" version), under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.
FEATURES Synchronous Controller in 8-Pin Package Operating with single 5V or 12V suppl...
