FAN5602 - Universal (Step-Up/Step-Down) Charge Pump Regulated DC/DC Converter

General Description

The FAN5602 is a universal switched capacitor DC/DC converter capable of step-up or step-down operation.

Due to its unique adaptive fractional switching topology, the device achieves high efficiency over a wider input/output voltage range than any of its predecessors.

Key Features

  • Low Noise Constant Frequency Operation at Heavy Load.
  • High Efficiency Pulse-Skip (PFM) Operation at Light Load.
  • Adaptive Seven Switch Configurations (1:3, 1:2, 2:3, 1:1, 3:2, 2:1, 3:1).
  • 92% Peak Efficiency.
  • Input Voltage Range: 2.7V to 5.5V.
  • Output Current:3.3V, 200mA at VIN = 3.6V.
  • ±3% Output Voltage Accuracy.
  • ICC < 1µA in Shutdown Mode.
  • 1MHz Operating Frequency.
  • Shutdown Isolates Output from Input.
