DESCRIPTION  
UTC P1785 consists of 2A step-down switching regulator  
control which includes a reference voltage source, oscillation  
circuit, error amplifier, internal PMOS and etc with PWM.  
UTC P1785 can provide low-ripple power, high efficiency, and  
excellent transient characteristics and an enable function, an over  
current protect function and a short circuit protect function are  
built inside, so the operation frequency will be reduced from  
300KHz to 30KHz when OCP or SCP happens. And the PWM  
control circuit can vary the duty ratio linearly from 100 down to  
0%. This converter also includes an error amplifier circuit as well  
as a soft-start circuit that prevents overshoot at startup. Also, to  
minimum external component count an internal compensation  
block is built in.

Halogen-free: P1785G  
P1785L  
These ICs can work as step-down switching regulators with the  
addition of an internal P-channel Power MOS, a coil, capacitors,  
and a diode connected externally. They provide such outstanding  
features: low current consumption. It is also suitable for the  
operation via an AC adapter because this converter can  
accommodate an input voltage up to 23V.
