UC3552 Overview
The UTC UC3552 is a step-up PWM DC-DC converter with a internal switch which is 1.6A, 0.23Ω. UTC UC3552 offers users flexibility in determining loop dynamics and adjusting operating frequency cause it’s equipped with an external pensation pin ,and it also allows the use of small, low equivalent resistance (ESR) ceramic output capacitors. UTC UC3552 is capable of converting a standard input of 3.3V to multiple...
