Stmicroelectronics (L5970D) DC-DC Switching Buck (Step Down) Regulator

DC-DC Switching Buck (Step Down) Regulator, Adjustable, 4.4V-36Vin, 1.2V-35Vout,1Aout, SOIC-8Product OverviewThe L5970D is a Step-down Monolithic Power Switching Regulator IC capable todeliver up to 1A at output voltages from 1.2 to 35V. The device uses an internalP-channel D-MOS transistor (with a typical Rdson of 250mR) as switching elementto minimize the size of the external components. Pulse by pulse current limitwith the internal frequency modulation offers an effective constant currentshort circuit protection.3.3V/(±2%) Reference voltageOperating input voltage from 4.4 to 36V100% Duty cycle low dropout operation250kHz Internally fixed frequencyVoltage feed forwardZero load current operationInternal current limitingInhibit for zero current consumptionSynchronizationProtection against feedback disconnectionThermal shutdownApplicationsConsumer Electronics, Communications & Networking, Computers & ComputerPeripheralsProduct InformationTopology: Buck (Step Down)Input Voltage Min: 4.4VInput Voltage Max: 36VNo. of Outputs: 1OutputsDC / DC Converter IC Case: SOICNo. of Pins: 8PinsOutput Current: 1AOutput Voltage Min: 1.2VOutput Voltage Max: 35VSwitching Frequency: 280kHzOperating Temperature Max: 150°CMSL: MSL 3 - 168 hours
