SP6669 - 600mA 1.5MHz Synchronous Step Down Converter

Datasheet Summary

Description

The SP6669 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 600mA of current.

Features

  • a pulse skip mode (PSM) for light load efficiency and a LDO mode for 100% duty cycle. With a 2.5V to 5.5V input voltage range and a 1.5MHz switching frequency, the SP6669 allows the use of small surface mount inductors and capacitors ideal for battery powered portable.

SP6669 600mA 1.5MHz Synchronous Step Down Converter May 2016 GENERAL DESCRIPTION The SP6669 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 600mA of current. It features a pulse skip mode (PSM) for light load efficiency and a LDO mode for 100% duty cycle. With a 2.5V to 5.5V input voltage range and a 1.5MHz switching frequency, the SP6669 allows the use of small surface mount inductors and capacitors ideal for battery powered portable applications. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.
