LM2650M-ADJ/NOPB

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-18В (Vin), 1.5В-16В, 3А, SOP-24.

The LM2650M-ADJ/NOPB is a synchronous step-down DC-to-DC Converter features 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 0.2 to 2A. A low-power hysteretic or sleep mode keeps efficiencies high at light loads. The LM2650 enters and exits sleep mode automatically as the load crosses sleep-in and sleep-out thresholds. The LM2650 provides nodes for programming both thresholds via external resistors.
