Renesas Electronics ISL85403FRZ-T7A, 1 Buck Boost, Voltage Regulator 800mA

The Renesas 2.5A Regulator is a 40V, 2.5A synchronous buck or boost buck controller with an integrated high-side MOSFET and low-side driver. In Buck mode it supports a wide input range of 3V to 40V. In Boost-Buck mode the input range can be extended down to 2.5V and output regulation can be maintained when VIN drops below Vout, enabling sensitive electronics to remain on in low input voltage conditions.

Buck mode of input voltage range 3V to 40V
Boost mode expands operating input voltage lower than 2.5V
Selectable forced PWM mode or PFM mode
Less than 5μA (max) shutdown input current (IC disabled)
