General Description

The AX3519 is a 1MHz constant frequency current mode PWM step-down converter.

It is ideal for portable equipment requiring very high current up to 4A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions.

The AX3519 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.

Key Features

2.8V to 5.5V Input Voltage Range Output Voltages from 0.8V to VIN High Efficiency: Up to 94% 1MHz Constant Frequency Operation With power saving mode Up to 4A Output Current No Schottky Diode Required Current Mode Operation for Excellent Line and Load Transient Response Current limit and thermal shutdown protection Short Circuit Protect (SCP) Build-in Soft Start function ≤ 5µA Shutdown Current SOP-8L-EP and TDFN-8 Pb-Free packages 1/12 AXElite Confidential Materials, do not copy or distribute w.
