Product Overview

STEVAL-L3751V12 is a 75V, 15A DC-DC converter buck regulator evaluation board with L3751 controller. The evaluation board is based on the L3751 synchronous buck controller, which implements the voltage mode in a VQFN package with internal compensation to minimize the design complexity and size. The diode emulation (DEM) implements the pulse-skipping mode, which maximizes the efficiency at light-load with a controlled output voltage ripple. The forced PWM (FPWM) over-the-load range makes the switching frequency constant and minimizes the output voltage ripple. The power good open collector output validates the regulated output voltage for monitoring. It implements the output voltage sequencing for digital ICs during the power-up phase. The embedded gate driver is designed for standard Vth MOSFET and minimizes the number of external components.
  • Selectable two-output voltage level 5V or 12V
  • 230kHz switching frequency setting
  • Low drop-out operation during line transient
  • Synchronization from 185 to 345KHz
  • Power good open collector output validates the VOUT
  • Constant current protection with hiccup mode
  • Current sensing on rds-on low-side
  • Improved line-transient response
  • Input voltage undervoltage lockout, internal voltage monitoring, thermal protection
  • Operating junction temperature range: -40 to 150°C
