150KHz, 3A PWM Buck DC/DC Converter + 1A Ultra Low  
Drop Regulator  
„ Features  
„ General Description  
* Channel 1: simple switch  
The Channel 1 is a step-down DC/DC converter,  
and own the ability of driving a 3A load 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  
- Adjustable version output voltage range, 1.23V to  
18V+4% & Fixed 3.3V version  
- 150KHz +20% fixed switching frequency  
- Voltage mode non-synchronous PWM control  
- ON/OFF shutdown control input  
- Operating voltage can be up to 20V  
- Output load current: 3A  
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  
- Low power standby mode  
* Channel 2: ultra low drop regulator  
- Adjustable output voltage  
- 0.6V Maximum Dropout voltage at 1.0A Load  
current  
- Fast transient response  
frequency will be reduced.  
The switching  
- Good noise rejection  
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 +20% on the oscillator  
frequency.  
* Channel 1 & Channel 2  
- SOP-16L Pb-free package  
- Built-in switching transistor on chip  
- Thermal-shutdown and current-limit protection of  
each channel  
„ Applications  
The channel 2 is a 1A regulator with extremely low  
dropout voltage. This product is specifically  
designed to provide well regulated supply for  
applications requiring 2.8V or lower voltages from  
3.3V power supplies where high efficiency of a  
switcher can be achieved without the cost and  
complexity associated with switching regulator.
