Switching frequency1000-3000 kHz
Output 15.5 V / 1 A
IC revisionA

Description

The LTC®3374A is a multioutput power supply IC consistingof eight synchronous 1A buck converters, all powered fromindependent 2.25V to 5.5V input supplies. An upgradedpin-compatible version of the LTC3374, the LTC3374A,has higher efficiency, improved output voltage accuracyand an added overvoltage (OV) indicator.

Features

8-Channel 1A Independent Step-Down DC/DCsMaster-Slave Configurable for Up to 4A of Output Current with a Single InductorIndependent VIN Supplies for Each DC/DC (2.25V to 5.5V)All DC/DCs Have 0.8V to VIN Output Range±1% VFB Accuracy, for Buck 1 (1A to 4A)±1% PGOOD AccuracyPrecision Enable Pin Thresholds for Autonomous Sequencing1MHz to 3MHz Programmable/Synchronizable Oscillator Frequency (2MHz Default)Die Temperature Monitor OutputThermally Enhanced 38-Lead 5mm × 7mm QFN and TSSOP PackagesPin-Compatible with LTC3374

Typical applications

  • Industrial/Automotive/Communications
  • General Purpose Multichannel Power Supplies
