Renesas Electronics ISL91127IIAZ-T7A, 1, Voltage Regulator 2.1A, 1 → 5.2 V, 2.5 MHz 20-Pin, WLCSP-20

The Renesas Electronics a high-current buck-boost switching regulator for systems using new battery chemistries. Tt uses proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output voltage.

Fully protected for short-circuit, over-temperature and under voltage
20 Ld 4mmx4mm QFN package
Accepts input voltages above or below regulated output voltage
Automatic and seamless transitions between buck and boost modes
