ZT1525 3A, 24V Asynchronous Step‐Down DC/DC Converter DESCRIPTION The ZT1525 is a constant frequency peak current‐mode step‐down switching regulator. The range of input voltage is from 4V to 24V. The output current is up to 3A. The switching frequency of the ZT1525 is programmable up to 2.5MHz, to achieve high input/output conversion ratio, and allowing the use of small inductors and ceramic capacitors for miniaturization. Peak current mode PWM control of the ZT1525 provides fast transient response with simple loop compensation. Cycle‐by‐cycle current limiting and hiccup overload protection reduces power dissipation during output overload. Soft‐start function reduces input start up current and prevents the output from overshooting during power up.
