LM2653MTC-ADJ/NOPB

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4В-14В (Vin), 1.5В-5В, 1.5А, TSSOP-16.

The LM2653MTC-ADJ/NOPB is a synchronous Switching Regulator provides high-efficient power conversion over a 100:1 load range. This feature makes the LM2653 an ideal fit in battery-powered applications. Synchronous rectification is used to achieve up to 97% efficiency. At light loads, the LM2653 enters a low power hysteretic or sleep mode to keep the efficiency high. In many applications, the efficiency still exceeds 80% at 15mA load. A shutdown pin is available to disable the LM2653 and reduce the supply current to 7µA. All the power, control and drive functions are integrated within the ICs. The ICs contain patented current sensing circuit for current-mode control. This feature eliminates the external current sensing resistor required by other current-mode DC-to-DC converters. The IC has a 300kHz fixed frequency internal oscillator. The high oscillator frequency allows the use of extremely small, low profile components.
