Technology Licensed from International Rectifier  
APU3037 / APU3037A  
8-PIN SYNCHRONOUS PWM CONTROLLER  
DESCRIPTION  
FEATURES  
Synchronous Controller in 8-Pin Package  
Operating with single 5V or 12V supply voltage  
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.  
Internal 200KHz Oscillator  
(400KHz for APU3037A)  
Soft-Start Function  
Fixed Frequency Voltage Mode  
500mA Peak Output Drive Capability  
Protects the output when control FET is shorted  
RoHS Compliant & Halogen-Free Product
