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 moderate to heavy loads from 0.2A to 2A.
Features
■ Ultra high efficiencies (95% possible)
