DC-DC Switching Buck (Step Down) Regulator, Adjustable, 4.4V-36Vin, 1.2V-35Vout, 1Aout, SOIC-8 Product Overview The L5970D is a Step-down Monolithic Power Switching Regulator IC capable to deliver up to 1A at output voltages from 1.2 to 35V. The device uses an internal P-channel D-MOS transistor (with a typical Rdson of 250mR) as switching element to minimize the size of the external components. Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short circuit protection. 3.3V/(±2%) Reference voltage Operating input voltage from 4.4 to 36V 100% Duty cycle low dropout operation 250kHz Internally fixed frequency Voltage feed forward Zero load current operation Internal current limiting Inhibit for zero current consumption Synchronization Protection against feedback disconnection Thermal shutdown Applications Consumer Electronics, Communications & Networking, Computers & Computer Peripherals Product Information Topology: Buck (Step Down) Input Voltage Min: 4.4V Input Voltage Max: 36V No. of Outputs: 1Outputs DC / DC Converter IC Case: SOIC No. of Pins: 8Pins Output Current: 1A Output Voltage Min: 1.2V Output Voltage Max: 35V Switching Frequency: 280kHz Operating Temperature Max: 150°C MSL: MSL 3 - 168 hours
