MAX8627 Datasheet Synchronous Boost Converter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. 19-3995; Rev 0; 3/06 KIT ATION EVALU E L B A IL AVA Low VBATT, 20µA IQ, 1MHz Synchronous Boost Converter with True.

General Description

The MAX8627 step-up converter is a high-efficiency, low-quiescent current, synchronous boost converter with True Shutdown™ and inrush current limiting.

The MAX8627 generates any boosted output voltage from 3V to 5V from either a 2-cell NiMH/NiCd or a single-cell Li+/Li polymer battery.

Quiescent current is only 20µA (typ), and at light loads the converter pulses only as needed for best efficiency.

Key Features

  • include True Shutdown, internal compensation, and adjustable current limit. The MAX8627 is available in a tiny 3mm x 3mm TDFN package and is ideal for use in handheld devices such as DSCs, PDAs, and smartphones.
  • 1MHz PWM Switching Frequency.
  • True Shutdown Output.
  • Up to 95% Efficiency.
  • 1.0A Guaranteed Output Current.
  • Soft-Start Eliminates Inrush Current.
  • 20µA (typ) Quiescent Current.
  • 0.1µA Logic-Controlled Shutdown.
  • Internal.
