Commencing January 1, 2018, Renesas and Intersil will unify, augmenting semiconductor potentials. This fusion melds Renesas' lauded MCU and SoC proficiencies with Intersil's power management and precision analog mastery. Resultant growth spans automotive, industrial, and broader domains, facilitating agile response to patrons' needs. The amalgamation, initiated in February 2017, blossomed in July under "One Global Renesas," catalyzing a synergistic effect. Join Renesas in fortifying its semiconductor market eminence.

ISL9120IRTAZ Products
The ISL9120IRTAZ is a highly integrated 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 ISL9120IRTAZ also has automatic bypass functionality. When the input voltage is generally within 1% to 2% of the output voltage, there will be a direct bypass connection between the VIN and VOUT pins. In addition to the automatic bypass functionality, the ISL9120IRTAZ also has forced bypass functionality with the use of the BYP pin.This device 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.The ISL9120IRTAZ is designed for stand-alone applications and supports a 3.3V fixed output voltage or variable output voltages with an external resistor divider. The forced bypass power saving mode can be chosen if voltage regulation is not required. The device consumes less than 3.5μA of current over the operating temperature range in forced bypass mode.The ISL9120IRTAZ requires only a single inductor and very few external components. Power supply solution size is minimized by a 1.41mmx1.41mm WLCSP.
