NCP1596A  
1.5 A, 1.5 MHz Current  
Mode PWM Buck Down  
Converter  
The NCP1596A is a current mode PWM buck converter with  
integrated power switch. It can provide up to 1.5 A output current with  
high conversion efficiency. High frequency PWM control scheme can  
provide a low output ripple noise. Thus, it allows the usage of small  
size passive components to reduce the board space. In a low load  
condition, the controller will automatically change to PFM mode  
which provides a higher efficiency at low load. Additionally, the  
device includes softstart, thermal shutdown with hysteresis,  
cyclebycyclecurrent limit, and short circuit protection. This device  
is available in a compact 3x3 DFN package.
