AP1551  
150KHz, Dual Channel 2A PWM Buck DC/DC Converter  
„ Features  
„ General Description  
- Dual adjustable output channel  
- Adjustable output voltage range, 1.23V to  
18V+4%  
The AP1551 is monolithic IC designed for dual  
channel step-down DC/DC converters, and own the  
ability of driving a 2A load each channel without  
additional transistor component. Due to reducing  
the number of external component, the board  
space can be saved easily. The external shutdown  
function can be controlled by logic level and then  
- 150KHz +15% fixed switching frequency  
- Voltage mode non-synchronous PWM control  
- Thermal-shutdown and current-limit protection  
- ON/OFF shutdown control input  
- Operating voltage can be up to 22V  
- Output load current: 2A  
come  
into  
standby  
mode.  
The  
internal  
compensation makes feedback control have good  
line and load regulation without external design.  
Regarding protected function, thermal shutdown is  
to prevent over temperature operating from damage,  
and current limit is against over current operating of  
the output switch. If current limit function occurred  
and VFB is down to 0.5V below, the switching  
frequency will be reduced. The AP1551 operates  
at a switching frequency of 150KHz thus allowing  
smaller sized filter components than what would be  
needed with lower frequency switching regulators.  
Other features include a guaranteed +4% tolerance  
on output voltage under specified input voltage and  
output load conditions, and +15% on the oscillator  
- SOP-16L Pb-Free packages  
- Low power standby mode  
- Built-in switching transistor on chip  
„ Applications  
- Simple High-efficiency step-down regulator  
- On-card switching regulators  
- Positive to negative converter  
frequency. The packages are available in  
standard 16-lead SOP-16 package.
