MAXM17900 4V to 24V, 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 24V Input supply solutions. The MAXM17900 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 Capability Internally Compensated and inductor that operates over a wide input voltage range. The module operates from 4V to 24V 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 MAXM17900 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 a default soft-start time Open-Drain Power Good Output (RESET Pin) of 5.1ms. Programmable EN/UVLO Threshold The MAXM17900 is available in a low profile, compact Rugged 10-pin 2.6mm x 3mm x 1.5mm uSLIC package.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note 1: Junction temperature greater than +125C degrades operating lifetimes Package Information PACKAGE TYPE: 10-PIN uSLIC Package Code M102A3+1 Outline Number 21-100094 Land Pattern Number 90-100027 THERMAL RESISTANCE FOUR-LAYER BOARD Junction to Ambient ( ) 30.6C/W JA For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages.
