Overview
UNISONIC TECHNOLOGIES CO.
, LTD UC3655 500mA SYNCHRONOUS STEP-DOWN DC/DC CONVERTERS  DESCRIPTION The UTC UC3655 is a synchronous-rectification type DC/DC converters with a built-in 0.
6Ω P-channel driver transistor and 0.
7Ω N-channel switching transistor, which designed to allow the use of ceramic capacitors.
Using only a coil and two capacitors connected externally, the UC3655 enable a high efficiency, stable power supply with an output current of 500mA to be configured.
Its operating voltage is 2.
0V and the output voltage is programmable in a range from 0.
9V to 4.
0V in increments of 0.
1V (accuracy: ±2.
0%) internally.
The oscillation frequency is 1.
3MHz.
For operation mode, it is PWM control in the UTC UC3655, the UTC UC3655 series is automatic PWM/PFM switching control, allowing fast response, low ripple and high efficiency over the full range of load.
Internal soft start and current control functions are built in it.
All circuits are shutdown to reduce current consumption to as low...
