ASP8A50QU

100V Input, 5A Output, Non-synchronous Step-down Converter

Features

Description

The ASP8A50QU is a high voltage, Non-synchronous

step-down controller operates over a wide range input



9V to 100V input voltage range

5A continuous output current

voltage 9V to 100V. The ASP8A50QU delivers 5A

continuous load current with up to 96% efficiency.

The ASP8A50QU operates with fixed frequency peak

current control with built-in compensation eliminates the

need for external components. Cycle-by-cycle current

limit in high-side MOSFET protects the converter in an

overload condition. Hiccup mode protection is triggered

if the over-current condition has persisted for longer

than the present time. The ASP8A50QU exhibits

protection features that protect the load from faults like

under-voltage, over-current and over-temperature.

The ASP8A50QU is available in an QFN-20.

96% Peak Efficiency

500µA operating quiescent current

Peak Current mode control

100V 20-mΩ high-side and low-side MOSFET

150 kHz Fixed Frequency

Internal compensation for ease of use

Up to 91% duty cycle
