LTC3376 20 V, 4-Channel Buck DC/DC Voltage Regulator

Analog Devices' regulators feature eight configurable 1.5 A power stages and are ideal for telecom applications

Image of Analog Devices' LTC3376 4-Channel Buck DC/DC Voltage RegulatorAnalog Devices' LTC3376 is part of the LTC337x configurable, multi-output, eight power stage, buck regulator family. The LTC3376 devices extend the maximum input voltage from 5.5 V to 20 V making them ideal for industrial and 12 V/18 V adapter applications. These regulators provide 15-pin selectable-output configurations (1.5 A to 12 A per channel), a wide input voltage range of 3 V to 20 V, a wide output voltage of 0.4 V to 0.83 VIN, and internal boost capacitors for reduced PCB space.

Features
  • Wide input voltage (VIN) range: 3 V to 20 V
  • Wide output voltage (VOUT) range: 0.4 V to 0.83 VIN
  • 8x 2.5 A buck power stages that can be configured with 1 to 4 output channels
  • 15 pin-selectable output configurations (1.5 A to 12 A per channel)
  • Internal boost capacitors for reduced PCB space
  • No-load IQ: 27 µA (1 buck-enabled), 42 µA (all bucks enabled)
  • VOUT accuracy: 1% on all channels
  • Peak-current-mode control (Burst-mode® operation/forced continuous)
  • Precision RUN input, individual PGOOD outputs for power sequencing
  • Frequency: 1 MHz to 3 MHz (RT programmable, PLL SYNC, or 2 MHz internal oscillator)
  • TEMP-pin output indicates the die temperature
  • Output current monitors
  • Differential output sense
Applications
  • Telecom/industrial
  • 12 V distributed power systems
