Analog Devices / Maxim Integrated MAX17524 Synchronous Step-Down DC-DC Converter

Analog Devices MAX17524 Synchronous Step-Down DC-DC Converter is a dual-output, high-efficiency, high-voltage converter with integrated high-side MOSFETs. The device operates over a 4.5V to 60V input-voltage range. The device delivers up to 3A on each output and generates output voltages from 0.9V up to 90% of VIN. The Analog Devices MAX17524 features internal compensation, uses peak current-mode control, and can be operated in pulse-width modulation (PWM), pulse-frequency modulation (PFM), and discontinuous-conduction mode (DCM). This feature enables high efficiency under light-load conditions with a feedback-voltage regulation accuracy to within ±1.4% over -40°C to +125°C. The Analog Devices MAX17524 Synchronous Step-Down DC-DC Converter is housed in a 32-pin (5mm x 5mm) Thin QFN (TQFN) package.
