MAXM17572AMC+

MAXM17572 is a Himalaya uSLIC step-down power module and charger enables cooler, smaller, and simpler power supply solutions. This is a high-efficiency, synchronous, Himalaya step-down DC-DC power module with integrated controller, MOSFETs, compensation components, and inductor that operates over a wide input-voltage range. The module significantly reduces design complexity and manufacturing risks, and offers a true “plug-and-play” power supply solution, reducing the time-to-market. This employs peak-current-mode control architecture. It offers programmable switching frequency, active-low RESET output voltage monitoring, adjustable input undervoltage lockout, and programmable soft-start. The module also features hiccup-mode overload protection and a thermal shutdown function. Application includes industrial power supplies, distributed supply regulation, FPGA and DSP point-of-load regulator, base station point-of-load regulator, HVAC and building control.

• Internally control loop compensated, all ceramic capacitors
• Flexible design, PWM mode of operation
• Adjustable frequency with external frequency synchronization (400KHz to 2.2MHz)
• Programmable soft-start, open-drain power good output (active-low RESET pin)
• Programmable EN/UVLO threshold, auxiliary bootstrap supply (EXTVCC) for improved efficiency
• Robust operation, over temperature protection, hiccup over current protection
• Complies with CISPR32 (EN55032) Class B, conducted and radiated emissions
• Input voltage range from 4.5 to 60V (VIN = VEN/UVLO = 24V, RRT/SYNC = 40.2kohm, TA = +25°C)
• Switching frequency range from 430 to 550KHz (RRT = OPEN, VIN = VEN/UVLO = 24V, TA = +25°C)
• 12-pin uSLIC package, temperature range from -40°C to +125°C
