Quantity

DC/DC Controller, Synchronous Buck (Step Down), 4.5 V to 42 V, 1 Output, 2.2 MHz, TQFN-20 Product Overview The MAX17543ATP+ is a 4.5V to 42V, 2.5A, high efficiency, synchronous step-down DC-DC converter with internal compensation in 20 pin TQFN package. The converter can 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. It uses 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 supply regulation, high voltage single board systems, base station power supply and general purpose point of load. Reduces number of DC-DC regulators to stock, adjustable 0.9V to 0.9 x VIN output 100KHz to 2.2MHz adjustable switching frequency with external synchronization Reduces power dissipation, peak efficiency > 90%, 2.8µA shutdown current PFM/DCM enables enhanced light-load efficiency, no schottky synchronous operation Operates reliably in adverse industrial environments, built-in soft start Peak current limit protection, internal compensation for any output voltage Built-in output voltage monitoring with RESET (complementary) Programmable EN/UVLO threshold Monotonic start-up into pre-biased load Overtemperature protection Applications Power Management, Industrial Product Information Supply Voltage Min: 4.5V Supply Voltage Max: 42V No. of Outputs: 1 Output Controller IC Case Style: TQFN No. of Pins: 20Pins Switching Frequency: 2.2MHz Topology: Synchronous Buck (Step Down) Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: Himalaya Series MSL: MSL 1 - Unlimited
