OCP2158 - 1.5MHz 700mA Synchronous Step-Down Converter

Download the OCP2158 datasheet PDF. This datasheet also covers the OCP2158-ORIENT variant, as both devices belong to the same 1.5mhz 700ma synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The OCP2158 is a 1.5MHz constant frequency, high efficiency, slope compensated current mode PWM step-down converter.

The devices integrate a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

Features

  • a Power Saving Mode which reduces quiescent current to just 30μA and significantly improves efficiency at light load.
  • The OCP2158 is offered in a low profile (1mm) 5-pin, SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.

WWW.ORIENT-CHIP.COM OCP2158 1.5MHz 700mA Synchronous Step-Down Converter with Low Quiescent Current ◼ General Description The OCP2158 is a 1.5MHz constant frequency, high efficiency, slope compensated current mode PWM step-down converter. The devices integrate a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The OCP2158 can operate from a 2.0V to 6.5V input voltage and is ideal for powering portable equipment that runs from a single cell lithium-ion (Li+) battery. It can supply 700mA output current and can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. The OCP2158 features a Power Saving Mode which reduces quiescent current to just 30μA and significantly improves efficiency at light load.
