3 Description

The LM2651 switching regulator provides high-

efficiency power conversion over a 100:1 load range (1.5 A to 15 mA). This feature makes the LM2651 an

ideal fit in battery-powered applications that demand

long battery life in both run and standby modes.

Synchronous rectification is used to achieve up to

97% efficiency. At light loads, the LM2651 enters a

low power hysteretic or sleep mode to maintain high

efficiency. In many applications, the efficiency still

exceeds 80% at 15-mA load. A shutdown pin is

available to disable the LM2651 and reduce the

supply current to less than 10 μA.

The LM2651 contains a patented current sensing

circuitry for current mode control. This feature

eliminates the external current sensing resistor

required by other current-mode DC-DC converters.

The LM2651 has a 300-kHz fixed frequency internal

oscillator. The high oscillator frequency allows the

use of extremely small, low-profile components.

A programmable soft-start feature limits current

surges from the input power supply at start-up and provides a simple means of sequencing multiple

power supplies.

Other protection features include input undervoltage

lockout, current limiting, and thermal shutdown.
