LM2651MTC-ADJ

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4В-14В (Vin), 3.3В-13В, 1.5А, TSSOP-16.

The LM2651MTC-ADJ is a Switching Regulator provides high-efficiency power conversion over a 100:1 load range. 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 15mA load. A shutdown pin is available to disable the LM2651 and reduce the supply current to less than 10µA. 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-to-DC converters. The LM2651 has a 300kHz fixed frequency internal oscillator. The high oscillator frequency allows the use of extremely small, low-profile components.
