XRP6657 Datasheet 1.5a 1.3mhz Synchronous Step Down Converter

Manufacturer: Exar (now MaxLinear)

Overview: February 2011 XRP6657 1.5A 1.3MHz Synchronous Step Down Converter Rev. 1.2.

General Description

The XRP6657 is a high efficiency synchronous step down DC to DC converter capable of delivering up to 1.5 Amp of current and optimized for portable battery-operated applications.

Operating over an input voltage range of 2.5V to 5.5V, it provides an adjustable regulated output voltage down to 0.6V.

The XRP6657 uses a constant 1.3 MHz frequency pulse width modulation (PWM) scheme allowing for pact external ponents, low output voltage ripple and fixed frequency noise, while Pulse Skip Mode (PSM) is used to improve light load efficiency.

Key Features

  • Guaranteed 1.5A Output Current.
  • Fixed 1.3MHz Frequency PWM Operations.
  • Up to 95% efficiency.
  • Input Voltage: 2.5V to 5.5V.
  • Adjustable Output Voltage.
  • Internal Compensation Network.
  • No Schottky Diode Required.
  • LDO Operation: 100% Duty Cycle.
  • 240μA Quiescent Current (no load).
  • 1μA Shutdown Current.
  • Soft Start Function.
  • Over-current/Over-temperature Protection.
  • “Green”/Halogen Free D.
