Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Mingjiada Electronics introduces the ISL9122AIIHZ a flexible boost switching regulator with bypass mode support that provides ultra-low quiescent current (IQ) for powering sensors, microcontrollers (MCUs), wireless devices and other system components.

The ISL9122A boost switching regulator has an I2C interface and programmable 25mV steps for dynamic voltage scaling (DVS) to optimise system power consumption. The regulator has a maximum output voltage of 5.375V to maximise the performance of RF-enabled IoT devices over the full battery voltage range. Its PFM and PWM functions maximise efficiency over the entire output current range. In forced PWM mode, the regulator maintains a switching frequency of 2.5MHz to improve system EMI performance.

Key Features

Ultra-low IQ 1.3 μA and low 7nA shutdown current for extended battery life

High efficiency (84%@10μA) at light loads and 97% peak efficiency to reduce power consumption and temperature rise

Automatic and selectable pass-through modes reduce IQ

Wide input voltage range of 1.8V to 5.5V for multiple battery-powered applications

Adjustable output voltage range of 1.8V to 5.375V in 25mV steps

Maximum output current up to 500mA (Vout=3.3V, Vin=3.6V)

Ultra-small 1.8mm x 1.0mm WLCSP or 3mm x 2mm DFN package saves board space

Requires only three external components: inductor, input capacitor and output capacitor

Comprehensive over-current, short-circuit and over-temperature protection

Target applications include wireless headphones, fitness devices, smart watches, water and gas meters, portable medical devices, and a variety of battery-powered smart IoT devices.
