ZSPM4023-09 DC/DC Buck Regulator

The ZSPM4023-09 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive on-time control architecture. The ZSPM4023-09 operates over a 4.5V to 28V supply range (24V typical). It has an internal linear regulator that provides a regulated 5V to power the internal control circuitry..

ZSPM4023-09 Features

* to ensure protection of the IC during fault conditions. These include under-voltage lockout to ensure proper operation under power-sag conditions; thermal shutdown; internal soft-start to reduce inrush current; foldback current limiting; and “hiccup” mode short-circuit protection.
