MAX17506ATP+

MAX17506ATP+ is a high-efficiency, synchronous step-down DC-DC converter with internal compensation. It is a high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 60V input. The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.4% over -40°C to 125°C. It uses peak current-mode control. The device can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), and discontinuous conduction mode (DCM) control schemes. Typical applications are industrial power supplies, distributed supply regulation, base station power supplies, wall transformer regulation, high-voltage single-board systems, general-purpose point-of-load.

• Reduces external components and total cost, no schottky-synchronous operation
• Internal compensation for any output voltage, all-ceramic capacitors, compact layout
• Reduce number of DC-DC regulators to stock
• Reduces power dissipation, peak efficiency <gt/> 95%, auxiliary bootstrap LDO for improved efficiency
• Operates reliably in adverse industrial environments, hiccup or latchoff mode overload protection
• DL to LX short detection feature, built-in output voltage monitoring with RESET
• Programmable EN/UVLO threshold, monotonic startup into prebiased load
• 20 TQFN EP package
• High industrial ambient operating temperature range from -40°C to +125°C
• 3.5µA shutdown current, overtemperature protection
