The ACT4088 is a current-mode step-down DC/DC converter that supplies up to 1.5A into 5V from a 12V input. 1.4MHz switching frequency allows the use of tiny external components, and internal loop ompensation provides simple, stable power supplies with a minimum of external components. Optimized for use with ceramic input and output capacitors, the ACT4088 provides a very compact 1.5A power supply for space constrained mobile and consumer applications.
The ACT4088 operates over a wide input voltage range and utilizes current-mode operation to provide excellent line and load transient response while requiring no external compensation components. Fault protection includes cycle-by-cycle current limiting, frequency fold-back, hiccup mode, and thermal shutdown. Internal soft-start provides a controlled startup with no overshoot, even at light loads.
The ACT4088 is available in a tiny SOT23-6 package and requires very few external components.
