Overview

LM2650 Synchronous Step-Down DC/DC Converter June 1999 LM2650 Synchronous Step-Down DC/DC Converter General Description The LM2650 is a step-down DC/DC converter featuring high efficiency over a 3A to milliamperes load range.
This feature makes the LM2650 an ideal fit in battery-powered applications that demand long battery life in both run and standby modes.
The LM2650 also features a logic-controlled shutdown mode in which it draws at most 25µA from the input power supply.
The LM2650 employs a fixed-frequency pulse-width modulation (PWM) and synchronous rectification to achieve very high efficiencies.
In many applications, efficiencies reach 95%+ for loads around 1A and exceed 90% for mo...
