LINEAR INTEGRATED CIRCUIT

DESCRIPTION  
UTC P1786 consists of 3A step-down switching regulator control  
which includes a reference voltage source, oscillation circuit, error  
amplifier, internal PMOS and etc with PWM.  
UTC P1786 can provide low-ripple power, high efficiency, and  
excellent transient characteristics. An enable function, an over  
current protect and short circuit protect function are built inside, so  
the operation frequency can be reduced from 300KHz to 30KHz  
when OCP or SCP happens. 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 counts  
for an internal compensation block is built in.  
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 accommodate  
an input voltage up to 23V.  
„
FEATURES
