Description
The RC5033 is a synchronous mode DC-DC controller IC dedicated to providing a 5V to 2.0V up to 3.6V conversion for various types of CPU power . It can be configured in both the synchronous and non-synchronous modes and with the proper applications circuitry can be used to deliver load current greater than 10 Amps. The RC5033 is designed to operate in a standard PWM control mode under heavy load conditions and as a PFM controller in light load conditions.
