Overview

Description

The ISL8502EVAL1Z evaluation board is used to evaluate the ISL8502 synchronous buck controllers with internal MOSFETs.

The ISL8502 device is a synchronous buck controller with internal MOSFETs packaged in a small 4mm x 4mm QFN package. It can support a continuous load of 2A and have a very wide input voltage range. With the switching MOSFETs integrated into the IC, the complete regulator footprint can be very small and provide a much more efficient solution than a linear regulator.

Features

  • 2A continuous output current
  • Integrated MOSFETs for small regulator footprint
  • Adjustable switching frequency, 500kHz to 1.2MHz
  • Tight output voltage regulation, ±1% over-temperature
  • Wide input voltage range, 5V ±10% or 5.5V to 14V
  • Wide output voltage range, from 0.6V
  • Simple single-loop voltage-mode PWM control design
  • Input voltage feed-forward for constant modulator gain
  • Fast PWM converter transient response
  • Lossless rDS(ON) high-side and low-side overcurrent protection
  • Undervoltage detection
  • Integrated thermal shutdown protection
  • Power-good indication
  • Adjustable soft-start
