A4003C - 3CH Power Management IC

General Description

The A4003C is a 3CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter.

It integrates three synchronous buck converters and can provide high efficiency output at light load and heavy load operation.

Key Features

  • 2.7V to 5.5V Input Voltage Range.
  • Three Buck Converters Output Voltage Range: 0.6V to Vin CH1, CH2, CH3 Continuous Load Current / Peak Current: 1A, 1A, 1A / 1.2A, 1.5A, 1.2A (3CH total output power consumption must be less than 6W) 180° Phases Shifted Architecture Fixed 1.5MHz Switching Frequency 100% Duty Cycle Low Dropout Operation.
