MSP1250 Power Converter Step-down Voltage Regulator

The MSP1250 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are avail-able in fixed output voltages of 3.3V, 5V, 12V, and an a.

MSP1250 Features

* include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80 µA standby current. Self-protection features include a two stage frequency reducing current limit
