AP2011  
Synchronous PWM with VFC Controller  
„ Features  
„ General Description  
- Single 10V to 40V Supply Application  
- 1.25V + 2.0% Voltage Reference  
The AP2011 is  
a
low-cost, full featured,  
synchronous voltage-mode controller designed for  
use in single ended power supply applications  
where efficiency is of primary concern.  
Synchronous operation allows for the elimination of  
heat sinks in many applications. The AP2011 is  
ideal for implementing DC/DC converters needed to  
power advanced microprocessors in low cost  
systems or in distributed power applications where  
efficiency is important. Internal level-shift, high-side  
drive circuitry, and preset shoot-thru control, allows  
the use of inexpensive 1P+1N-channel power  
switches.  
- Virtual Frequency ControlTM  
- Fast Transient Response.  
.
- Synchronous Operation for High Efficiency  
- Current Limit Function.  
- Small Size with Minimum External Components  
- Soft Start and Shutdown Functions  
- Industrial Temperature Range  
- Under Voltage Lockout Function  
- SOP-14L Pb-Free Package  
„ Applications  
AP2011’s features include temperature ompensated  
voltage reference, Virtual Frequency ControlTM method  
to reduce external component count, an internal virtual  
frequency 200KHz oscillator, under-voltage lockout  
protection, soft-start, shutdown function and current  
sense comparator circuitry.  
- Microprocessor Core Supply  
- Low Cost Synchronous Applications  
- Voltage Regulator Modules (VRM)  
- Networking Power Supplies  
- Sequenced Power Supplies  
- Telecommunication Power Supplies.
