FAN53202 Datasheet Digitally Programmable Regulator

Manufacturer: Fairchild (now onsemi)

Overview: FAN53202 — 5 A. 2.4 MHz, Digitally Programmable TinyBuck® Regulator April 2015 FAN53202 5 A, 2.

General Description

The FAN53202 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5 V to 5.5 V.

The output voltage is programmed through an I2C interface capable of operating up to 3.4 MHz.

Using a proprietary architecture with synchronous rectification, the FAN53202 is capable of delivering 5 A continuous at over 80% efficiency, while maintaining over 80% efficiency at load currents as low as 10 mA.

Key Features

  • Up to 91% Efficiency.
  • Quiescent Current in PFM Mode: 60 µA (Typical).
  • Digitally Programmable Output Voltage: - 0.6-1.3875 V in 12.5 mV Steps.
  • Best-in-Class Load Transient.
  • Continuous Output Current Capability: 5 A.
  • 2.5 V to 5.5 V Input Voltage Range.
  • Programmable Slew Rate for Voltage Transitions.
  • Fixed-Frequency Operation: 2.4 MHz.
  • I2C-Compatible Interface Up to 3.4 Mbps.
  • Internal Soft-Start.
  • Input Under-Voltage Lockout (UVLO).
  • Therma.
