Stmicroelectronics (L4971D) DC-DC Switching Buck (Step Down) Regulator

DC-DC Switching Buck (Step Down) Regulator, Adjustable, 8V-55Vin, 3.3V-50Vout, 1.5Aout, SOIC-16 Product Overview The L4971D is a step down monolithic Power Switching Regulator delivering 1.5A at a voltage between 3.3 and 50V. Realized in BCD mixed technology, the device uses an internal power D-MOS transistor (with a typical RDS (ON) of 0.25R) to obtain very high efficiency and high switching speed. The device is available in plastic dual in line, DIP8 for standard assembly and SO16W for SMD assembly. Voltage feed forward Zero load current operation Internal current limiting Inhibit for zero current consumption Protection against feedback disconnection Thermal shutdown Soft start function Applications Power Management Product Information Topology: Buck (Step Down) Input Voltage Min: 8V Input Voltage Max: 55V No. of Outputs: 1Outputs DC / DC Converter IC Case: SOIC No. of Pins: 16Pins Output Current: 1.5A Output Voltage Min: 3.3V Output Voltage Max: 50V Switching Frequency: 300kHz Operating Temperature Max: 150°C
