Shenzhen Mingjiada Electronics Co., Ltd. imported original [Supply Power IC] Professional PMIC ISL91212BIIZ-T Buck Switching Regulator IC Positive Programmable 0.3V 4 Output 5A 35-WFBGA, WLCSP


ISL91212BIIZ-T Device Description:

The ISL91212B is a four-phase, four-output programmable PMIC. they are optimised with highly efficient synchronous buck converters and are capable of multi-phase and single-phase operation with continuous output currents up to 5A per phase. they feature four buck controllers and can reconfigure their power stages to these controllers. This flexibility allows for seamless design for a wide range of applications requiring high output power and small solution sizes.


Chip features:

- Three output 2+1+1 phase (ISL91212A) or four output 1+1+1+1 single phase (ISL91212B)

- 2.5V to 5.5V supply voltage

- Output current capability of 5A per phase

- Small solution size (7x10mm2 for 4-phase design)

- High efficiency (94.7% for 3.8VIN/1.8VOUT)

- Low IQ in low power mode

- Patented control scheme reduces output capacitance and supports fast load transients (e.g. 50A/µs per phase)

- System accuracy ±0.7% with remote voltage sensing

- Programmable PWM frequency from 2MHz to 6MHz

- Programmable I2C outputs from 0.3V to 2V

- Independent dynamic voltage scaling (DVS) for each output

- Soft start and fault detection (UV, OV, OC, OT), short circuit protection

- 2.551mmx3.67mm 35-ball WLCSP with 0.5mm pin spacing


Applications:

- Smartphones, AR/VR glasses, drones

- Optical transceiver modules

- Artificial intelligence (AI) processors

- Customer / Enterprise / Data Centre SSD, NAS
