LM25190-Q1 CCCV Buck Controller Evaluation Module

Overview

TopologyBuck Converter
Input voltage5.5-42 V
Output 15 V / 5 A

Description

The LM25190QEVM-2100 evaluation module (EVM) is a synchronous buck DC/DC regulator with constantcurrent constant-voltage (CCCV) regulation. The EVM operates over a wide input voltage range of 5.5V to 42V (at J1 VIN terminal), providing a regulated current of 5A in CC mode and a regulated voltage of 5V in CV mode. The regulation target of the average inductor current is programmed by ISET and the output voltage is adjusted by modifying the feedback resistors.

Features

Wide input voltage operating range– 5.5V to 42V: VIN terminal

  • 5V output as a default. The EVM providesfootprints for fixed 12V, 5V, or adjustable outputvoltage.
  • Adjustable average inductor current using ISET
  • Inductor current monitor using IMON
  • Integrated standard MOSFET gate drivers
  • 35µA standby current at VSUPPLY = 12V (BIAS isnot connected to VOUT)
  • Full-load efficiency of 92% at VSUPPLY = 12V
  • 2100kHz switching frequency with optionalexternal clock synchronization
  • Dual-random spread spectrum
  • Integrated slope compensation
  • Forced PWM (FPWM) or pulsed-frequencymodulation (PFM) operation
  • Overcurrent protection (OCP) with hiccup mode forabnormal overload conditions
  • Power-Good indicator with pullup resistor to VCC
  • Internal 2.75ms soft start in CV mode
  • CC mode soft start using CISET capacitor
  • Thermally efficient layout with 6-layer 2oz PCB

Typical applications

  • Server battery-backup unit (BBU)
  • Super capacitor energy backup
  • Power tools
  • E-bikes
  • Energy storage system and solar energy
