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.
Application
Car Chargers
Adapters
ASP8434W is a stable and reliable constant
voltage constant current step-down DC-DC
converter with excellent performance.
