Renesas Electronics launched the ISL9122A, a versatile buck-boost switching regulator with bypass mode that gives ultra-low quiescent present (IQ) for powering sensors, microcontrollers (MCUs), wi-fi units, and different system parts. Working with battery output from 1.8V to five.5V, the ISL9122A extends the battery lifetime of sensible IoT units powered by coin-cell, lithium and a number of collection alkaline batteries. Goal purposes embrace wi-fi earbuds, health bands, sensible watches, water and gasoline meters, moveable medical units, and a variety of battery-operated sensible IoT units.
The ISL9122A buck-boost switching regulator implements dynamic voltage scaling (DVS) in I2C programmable 25mV steps to optimize system energy consumption. The regulator’s energy increase as much as 5.375V maximizes RF capabilities of IoT units throughout their battery vary. Its PFM and PWM performance maximizes effectivity over the entire output present vary. In compelled PWM mode, the regulator all the time switches at 2.5MHz frequency, which improves EMI efficiency of the system.
“With the explosive progress of IoT wi-fi connectivity purposes, the ISL9122A buck-boost regulator’s quick transitions from no load to full load is right for powering the latest era of units,” mentioned Andrew Cowell, Vice President, Mobility, Infrastructure and IoT Energy Enterprise Division at Renesas. “Our prospects reward the ISL9122A’s flexibility, dynamic voltage scaling and lowest regulated standby energy consumption.”
