RT8074 - Synchronous Step-Down Converter

Datasheet Summary

Description

The RT8074 is a simple, easy-to-use current mode controlled 4A synchronous step-down DC-DC converter with an input supply voltage range from 2.7V to 5.5V.The device build-in an accurate 0.8V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in SOP-8 (Exposed Pad)

Features

  • cycle-by-cycle current-limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation. Built-in softstart function prevents inrush current during start-up. The device also features input under-voltage lockout, output under-voltage protection, and over-temperature protection to provide safe and smooth operation in all operating conditions. Ordering Information RT8074 Package Type SP : SOP-8 (Exposed Pad-Option 2) Lead Plating Syste.

® RT8074 4A, 2MHz, Synchronous Step-Down Converter General Description The RT8074 is a simple, easy-to-use current mode controlled 4A synchronous step-down DC-DC converter with an input supply voltage range from 2.7V to 5.5V.The device build-in an accurate 0.8V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in SOP-8 (Exposed Pad) package. The RT8074 operates in automatic PSM that maintains high efficiency during light load operation. The device features cycle-by-cycle current-limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation. Built-in softstart function prevents inrush current during start-up.
