SG1577A  
Dual Synchronous DC/DC Controller  
Features  
Description  
The SG1577A is a high-efficiency, voltage-mode, dual-  
channel, synchronous DC/DC PWM controller for two  
independent outputs. The two channels are operated  
out of phase. The internal reference voltage is trimmed  
to 0.7V±1.5%. It is connected to the error amplifier’s  
positive terminal for voltage feedback regulation.

Integrated Two Sets of MOSFET Drivers

Constant Frequency Operation: Free-running Fixed  
Frequency Oscillator Programmable: 61kHz to 340kHz

Maximum Input Supply Voltage: 15V  
Programmable Output as Low as 0.7V  
The soft-start circuit ensures the output voltage can be  
gradually and smoothly increased from zero to its final  
regulated value. The soft-start pin can also be used for  
chip-enable function. When two soft-start pins are  
grounded, the chip is disabled and the total operation  
current can be reduced to under 0.7mA.  
Internal Error Amplifier Reference Voltage:  
0.7V±1.5%

20-Pin SOP  
The fixed-frequency is programmable from 60kHz to  
340kHz. The Over-Current Protection (OCP) level can  
be programmed by an external current sense resistor. It  
has two integrated sets of internal MOSFET drivers.  
SG1577A is available in a 20-pin SOP package.
