APW7061  
Synchronous Buck PWM Controller  
Features  
General Description  
The APW7061is a voltage mode, synchronous PWM  
controller which drives dual N-channel MOSFETs. It  
integrates the controls, monitoring and protection  
functions into a single package, which provides one  
controlled power outputs with under-voltage and  
over-current protections.  
·
·
Fast Transient Response  
- 0~85% Duty Ratio  
Excellent Output Voltage Regulation  
- 0.8V Internal Reference  
- ±1% Over Line Voltage and Temperature  
Internal Soft-Start  
·
·
APW7061 provides excellent regulationfor output load  
variation. An internal 0.8V temperature-compensated  
reference voltage is designed to meet the various low  
output voltage applications.  
- Typical 2mS  
Over Current Protection  
- Sense Low-side MOSFET’ s RDS(ON)  
Under Voltage Lockout  
A power-on-reset (POR)circuit limits the VCC minimum  
opearting supply voltage to assure the controller

Small Converter Size  
working well. Over current protection is achieved by  
monitoring the voltage drop across the low side  
MOSFET, eliminating the need for a current sensing  
resistor and short circuit condition is detected through  
- 250kHz Free-running Oscillator  
8-lead SOIC Package

the FB pin. The over-current protection triggers the  
soft-start function until the fault events be removed,  
but Under-voltage protection will shutdown IC directly.  
Applications  
Pull the COMP pin below 0.4V will shutdown the  
controller, and both gate drive signals will be low.
