LM2744 Datasheet (National Semiconductor) - Low Voltage N-Channel MOSFET Synchronous Buck Regulator Controller

LM2744, Low Voltage N-Channel MOSFET Synchronous Buck Regulator Controller

The LM2744 is a high-speed synchronous buck regulator controller with an externally adjustable reference voltage (between 0.5V to 1.5V).

It can provide simple down conversion to output voltages as low as 0.5V.

Though the control sections of the IC are rated for 3 to 6V, the driver sections are desig

LM2744 Features

* include soft-start, input undervoltage lockout (UVLO) and Power Good (based on both undervoltage and overvoltage detection). In addition, the shutdown pin of the IC can be used for providing startup delay, and the soft-start pin can be used for implementing precise tracking, for the purpose of seque
