AX3504A - 2A Synchronous Step-Down Converter

Download the AX3504A datasheet PDF. This datasheet also covers the AX3504 variant, as both devices belong to the same 2a synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The AX3504/A is a 1.2MHz constant frequency current mode PWM step-down converter.

It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions.

AX3504/A 1.2MHz, 2A Synchronous Step-Down Converter ™ GENERAL DESCRIPTION The AX3504/A is a 1.2MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The AX3504/A also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications. The AX3504/A can supply up to 2A output load current from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low as 0.6V. The high switching frequency minimizes the size of external components while keeping switching losses low.
