LM5122Z - Wide-Input Synchronous Boost Controller

Download the LM5122Z datasheet PDF. This datasheet also covers the LM5122 variant, as both devices belong to the same wide-input synchronous boost controller family and are provided as variant models within a single manufacturer datasheet.

Description

The LM5122 is a multi-phase capable synchronous boost controller intended for high-efficiency synchronous boost regulator applications.

The control method is based upon peak-current-mode control.

Features

  • 1 Maximum Input Voltage: 65 V.
  • Minimum Input Voltage: 3 V (4.5 V for Start-Up).
  • Output Voltage up to 100 V.
  • Bypass (VOUT = VIN) Operation.
  • 1.2-V Reference with ±1% Accuracy.
  • Free-Run and Synchronizable Switching to 1 MHz.
  • Peak-Current-Mode Control.
  • Robust 3-A Integrated Gate Drivers.
  • Adaptive Dead-Time Control.
  • Optional Diode-Emulation Mode.
  • Programmable Cycle-by-Cycle Current Limit.
  • Hiccu.
