2A Synchronous Buck Regulator with Integrated MOSFETs Evaluation Boards

描述

The ISL8502AEVAL1Z and ISL8502EVAL1Z evaluation boards are used to evaluate the ISL8502 and ISL8502A synchronous buck controllers with internal MOSFETs.

The ISL8502 and ISL8502A are synchronous buck controllers with internal MOSFETs packaged in a small 4mm x 4mm QFN package. They 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. Power-good (PGOOD) delay for ISL8502A has been decreased to 1ms typical (at 500kHz switching frequency) compared to 250ms (at 500kHz) for ISL8502.

主要特性

  • 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

应用

  • Point-of-load (POL) applications
  • Graphics cards - GPU and memory supplies
  • ASIC power supplies
  • Embedded processor and I/O supplies
  • DSP supplies
