ISL81401, ISL81401A

40V 4-Switch Synchronous Buck-Boost Controller

FN9310

Rev.1.01

Jan 27, 2022

The ISL81401 and ISL81401A are 4-switch synchronous

buck-boost controller with peak and average current

sensing and monitoring at both ends. The ISL81401 is a

bidirectional device that can conduct current in both

directions while the ISL81401A is an unidirectional

device.

Features

• Single inductor 4-switch buck-boost controller

• On-the-fly bidirectional operation with independent

control of voltage and current on both ends

• Proprietary algorithm for smoothest mode transition

The ISL81401 and ISL81401A use the proprietary

buck-boost control algorithm with valley current

modulation for Boost mode and peak current modulation

for Buck mode control.

• MOSFET drivers with adaptive shoot-through

protection

• Wide input voltage range: 4.5V to 40V

• Wide output voltage range: 0.8V to 40V

• Supports pre-biased output with SR soft-start

• Programmable frequency: 100kHz to 600kHz

The ISL81401 and ISL81401A have four independent

control loops for input and output voltages and currents.

Inherent peak current sensing at both ends and

cycle-by-cycle current limit of this family of products

ensures high operational reliability by providing instant

current limit in fast transient conditions at either ends and

in both directions. It also has two current monitoring pins

at both input and output to facilitate Constant Current

(CC) limit and other system management functions. CC

operation down to low voltages avoids any runaway

condition at over load or short-circuit conditions. In

addition to multilayer overcurrent protection, it also

provides full protection features such as OVP, UVP, OTP,

and average and peak current limit on both input and

output to ensure high reliability in both unidirectional

and bidirectional operation.

• Supports parallel operation current sharing with

cascade phase interleaving

• External sync with clock out or frequency dithering

• External bias for higher efficiency supports 5V - 36V

input

• Output and input current monitor

• Selectable PWM mode operation between

PWM/DE/Burst modes

• Accurate EN/UVLO and PGOOD indicator

• Low shut down current: 2.7µA

The IC is packaged in a space conscious 32 Ld

5mmx5mm QFN package to improve thermal dissipation

and noise immunity. The unique DE/Burst mode at

light-load dramatically lowers standby power

consumption with consistent output ripple over different

load levels.

• Complete protection: OCP, SCP, OVP, OTP, and UVP

• Dual-level OCP protection with average current

and pulse-by-pulse peak current limit

• Selectable OCP response with either hiccup or

constant current mode

• Negative pulse-by-pulse peak current limit
