TYPICAL APPLICATION
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-volt-
age lockout for both Vcc and Vc supplies, an external
programmable soft-start function as well as output un-
der-voltage detection that latches off the device when an
output short is detected.
