Maxim Integrated (MAX17543ATP+) DC/DC Controller, Synchronous Buck

DC/DC Controller, Synchronous Buck (Step Down), 4.5 V to 42 V, 1 Output, 2.2MHz, TQFN-20Product OverviewThe MAX17543ATP+ is a 4.5V to 42V, 2.5A, high efficiency, synchronous step-downDC-DC converter with internal compensation in 20 pin TQFN package. The convertercan deliver up to 2.5A and generates output voltages from 0.9V up to 0.9 x VIN.The feedback (FB) voltage is accurate to within ±1.1% over -40°C to +125°C. Ituses peak current-mode control and can be operated in the pulse width modulation(PWM), pulse frequency modulation (PFM) or discontinuous conduction mode (DCM)control schemes. It is used in industrial power supplies, distributed supplyregulation, high voltage single board systems, base station power supply andgeneral purpose point of load.Reduces number of DC-DC regulators to stock, adjustable 0.9V to 0.9 x VIN output100KHz to 2.2MHz adjustable switching frequency with external synchronizationReduces power dissipation, peak efficiency > 90%, 2.8µA shutdown currentPFM/DCM enables enhanced light-load efficiency, no schottky synchronousoperationOperates reliably in adverse industrial environments, built-in soft startPeak current limit protection, internal compensation for any output voltageBuilt-in output voltage monitoring with RESET (complementary)Programmable EN/UVLO thresholdMonotonic start-up into pre-biased loadOvertemperature protectionApplicationsPower Management, IndustrialProduct InformationSupply Voltage Min: 4.5VSupply Voltage Max: 42VNo. of Outputs: 1 OutputController IC Case Style: TQFNNo. of Pins: 20PinsSwitching Frequency: 2.2MHzTopology: Synchronous Buck (Step Down)Operating Temperature Min: -40°COperating Temperature Max: 125°CProduct Range: Himalaya SeriesMSL: MSL 1 - Unlimited
