24V/8A Synchronous EZBuck Regulator

General Description

Features

The AOZ1237 is a high-efficiency, easy-to-use DC/DC

synchronous buck regulator that operates up to 24V.

The device is capable of supplying 8A of continuous

output current with an output voltage adjustable down to

0.8V (±1.0%).



Wide input voltage range

– 2.7V to 24V



8A continuous output current

Output voltage adjustable down to 0.8V (±1.0%)

Low R

internal NFETs

DS(ON)

A proprietary constant on-time PWM control with input

feed-forward results in ultra-fast transient response while

maintaining relatively constant switching frequency over

the entire input voltage range. The switching frequency

can be externally programmed up to 1MHz.

– 35m high-side

– 8m low-side SRFET™

Constant On-Time with input feed-forward

Programmable frequency up to 1MHz

Selectable PFM light load operation

Ceramic capacitor stable



The device features multiple protection functions such as

under-voltage lockout, cycle-by-cycle current limit,

output over-voltage protection, short-circuit protection, as

well as thermal shutdown.

Adjustable soft start

Power Good output

Integrated bootstrap diode

Cycle-by-cycle current limit

Short-circuit protection

The AOZ1237 is available in a 4mm x 4mm QFN-23L

package and is rated over a -40°C to +85°C ambient

temperature range.

Over voltage protection
