ML4854 - Adjustable / Low-Current / 2-Cell Boost Regulator with Shutdown and Low Battery Detect

Description

The ML4854 is a low power boost regulator designed for low voltage DC to DC conversion in two-cell battery powered systems such as cell phones and PDAs.

The converter starts up at 1.3V and has an operating input voltage range from 1.6V to 4.5V.

Features

  • 95% Efficiency at 200mA Load Current Integrated Peak Current Limit Variable Output Voltage Determined by External Resistors Variable On-time Pulse Frequency Modulation (PFM) Fully Internal Synchronous Rectifier (no external diodes) for High Efficiency and Low Peak Currents.
  • Low-Battery Detection.
  • Logic Controlled Shutdown with True Load Disconnect General.
