LTC3890 Overview

Key Specifications

Package: SSOP
Pins: 28
Max Voltage (typical range): 60 V
Min Voltage (typical range): 4 V

Description

The LTC®3890 is a high performance dual step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phaselockable frequency of up to 850kHz.

Key Features

  • Low Operating IQ: 50µA (One Channel On)
  • Wide Output Voltage Range: 0.8V ≤ VOUT ≤ 24V
  • RSENSE or DCR Current Sensing
  • Out-of-Phase Controllers Reduce Required Input Capacitance and Power Supply Induced Noise
  • Phase-Lockable Frequency (75kHz to 850kHz)
