1.2A, 24V, 1.4MHz Step-down Converter
Description
AE2359
The AE2359 is a current mode step-down converter with a built-in power MOSFET to enable
smallest solution size power conversion.
With the low series resistance power switch it enables a constant output current of up to 1.2A over a
wide input supply range. The load and line regulation has excellent response time over the operating
input voltage and temperature range.
The AE2359 is self protected, through a cycle-by-cycle current limiting algorithm and an on chip
thermal protection.
The AE2359 will provide the voltage conversion with a low count of widely available standard
external components.
