MAXM17552 4V to 60V, 100mA, Compact Step-Down Power Module General Description Benefits and Features The Himalaya series of voltage regulator ICs and power Easy to Use modules enable cooler, smaller, and simpler power- Wide 4V to 60V Input supply solutions. The MAXM17552 is a high-efficiency, Adjustable 0.9V to 5.5V Output 1.75% Feedback-Voltage Accuracy synchronous, step-down DC-DC power module with inte- grated controller, MOSFETs, compensation components, Up to 100mA Output Current Internally Compensated and inductor that operates over a wide input-voltage range. The module operates from 4V to 60V input voltage All Ceramic Capacitors and delivers up to 100mA output current over a program- High Efficiency mable output voltage from 0.9V to 5.5V. The module sig- Fixed-Frequency PWM nificantly reduces design complexity, manufacturing risks Pulse Frequency Modulation (PFM) Mode to and offers a true plug and play power supply solution, Enhance Light-Load Efficiency reducing the time-to-market. Shutdown Current as Low as 1.2A (typ) The MAXM17552 employs peak-current-mode control Flexible Design architecture. To reduce input inrush current, the device Programmable Soft-Start and Prebias Startup offers a soft-start feature including the default soft-start Open-Drain Power Good Output (RESET Pin) time of 5.1ms. Programmable EN/UVLO Threshold The MAXM17552 is available in a low profile, compact Rugged TM 10-pin 2.6mm x 3mm x 1.5mm uSLIC package. Complies with CISPR22 (EN55022) Class B Conducted and Radiated Emissions.
