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. The AX3519 can supply up to 4A output load current from a 2.8V to 5.5V input voltage and the output voltage can be regulated as low as 0.8V. The high switching frequency minimizes the size of external components while keeping switching losses low. The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation. The AX3519 is
available in adjustable (0.8V to VIN) output voltage. The device is available in SOP-8L-EP and TDFN-8 Pb-free packages.
