Product Overview

The ISL91127IRN-EVZ is an evaluation board to evaluate ISL91127IRNZ 3.3V fixed output voltage regulator IC. This ISL91127IR is a high efficiency buck-boost 4.5A switching regulator for systems using new battery chemistries. It uses intersil's proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when input voltage is close to output voltage. The ISL91127IR supports standalone applications with an adjustable output voltage. The output voltages as low as 1V or as high as 5.2V are supported using an external resistor divider. It is used in brownout free system voltage for smart phones and tablet PCs and 2G/3G/4G RF power amplifiers.
  • Automatic and seamless transitions between buck and boost modes
  • Input voltage range from 1.8V to 5.5V
  • High efficiency up to 96%
  • 30µA quiescent current maximizes light load efficiency
  • 2.5MHz switching frequency minimizes external component size
  • Fully protected for short-circuit, over-temperature and undervoltage
  • Operating temperature of ISL91127IRAN range from -40°C to +85°C
  • Output current up to 2A (PVIN = 2.5V, VOUT = 3.3V)
  • Burst current up to 3A (PVIN = 3V, VOUT = 3.3V, tON < 600µs, t = 4.6ms)
  • ISL91127IRNZ is 20 pin 4mm x 4mm QFN package
