RC5033

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. Its highly accurate low TC reference eliminates the need for precision external components in order to achieve tight tolerance voltage regulation. Through the use of external resistors, the RC5033 can generate accurate output voltages from 2.0V up to 3.6V. An integrated Over-Voltage protection function constantly monitors the output voltage and shuts down the power to the CPU in the event of a out-oftolerance voltage situation, thereby protecting the CPU. The programmable oscillator can operate from 200KHz to greater than 1MHz to provide for flexibility in choosing external components such as inductors, capacitors, and Power MOSFETs.
