G5503 - 3A Buck Converter

General Description

The G5503 is a voltage-mode buck PWM converter capable of driving up to 3A loads over a wide input supply range.

High efficiency is obtained through the use of a low RDS(ON) P-channel power switch.

Key Features

  • Voltage Mode Asynchronous PWM Control.
  • 3.3V, 5V and Adjustable Output Version.
  • Operation Voltage can be up to 20V.
  • Adjustable Version Output Voltage Range, 0.8V to 16V±2%.
  • 300KHz Fixed Frequency Internal Oscillator.
  • Built-in Switching Transistor on Chip.
  • 3A Output Load Current.
  • Thermal Shutdown and Current Limit Protec- tion.
  • ON/OFF Shutdown Control.
  • Iq of Low Power Standby Mode 1µA.
  • Available in.
