ASP8434W

40V，3A ，CC and CV Synchronous Buck DC/DC Converter



Perfect Solution for Car Charger

Description

Input voltage withstand up to 40V

Built in 50mΩ high side PMOS

ASP8434W is a step-down DC-DC converter with

input withstand voltage up to 40V and can realize

accurate constant voltage and constant current.

ASP8434W has built-in 50mΩ high side PMOS

and 30mΩ low side NMOS, which can support

3A continuous output current, adjustable output

voltage and 100% duty cycle at most.

Built in 30mΩ low side NMOS

Support 3A continuous output current

Support 100% duty cycle

Output voltage and can be set (2.5V~22V)

Constant current accuracy ±5%

Constant voltage accuracy ± 1%

ASP8434W has high-performance load response

and input voltage response. At the same time, the

accurate constant voltage and constant current

control loop realizes minimal load adjustment rate

and linear adjustment rate.

No external compensation is required

135KHz fixed switching frequency

Cable compensation voltage drop

Short circuit protection (SCP), overheating

protection (OTP), over voltage protection

(OVP) and under voltage protection (UVLO)

Available Packages: ESOP-8

ASP8434W does not need external compensation.

It can realize constant current and constant voltage

control by relying on its own built-in stable loop.

At the same time, it has the function of cable

voltage drop compensation.
