Product Overview

The ISL9120IRN-EVZ is an evaluation board to evaluate ISL9120IRNZ 3.3V fixed output voltage regulator IC. This ISL9120IR is a compact high efficiency low power buck-boost switching regulator that accepts input voltages either above or below the regulated output voltage. This regulator automatically transitions between buck and boost modes without significant output disturbance. The ISL9120IR also has automatic bypass functionality for when the input voltage is generally within 1% to 2% of output voltage, there will be a direct bypass connection between VIN and VOUT pins. In addition to the automatic bypass functionality, the ISL9120IR also has forced bypass functionality with use of BYPS pin. The ISL9120IR is capable of delivering up to 800mA of output current (VIN = 2.5V, VOUT = 3.3V) and provides excellent efficiency due to its adaptive current limit pulse frequency modulation (PFM) control architecture. It is for stand-alone applications and supports a 3.3V fixed output voltage.
  • Automatic and seamless transitions between buck and boost modes
  • Input voltage range from 1.8V to 5.5V
  • High efficiency up to 98%
  • 41µA quiescent current maximizes light-load efficiency
  • Automatic bypass mode functionality
  • Fully protected for over-temperature and undervoltage
  • Operating temperature of ISL91127IRTNZ range from -40°C to +85°C
  • Output current up to 800mA (VIN = 2.5V, VOUT = 3.3V)
  • Adaptive multilevel current limit scheme to optimize efficiency at low and high currents
  • ISL9120IR is 12 pin 3mm x 3mm TQFN package
