MAXM17904/MAXM17905/ 4.5V to 24V, 300mA Himalaya uSLIC MAXM17906 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-supply Wide 4.5V to 24V Input solutions. The MAXM17904/MAXM17905/MAXM17906 Adjustable 0.9V to 6.3V Output Fixed 3.3V and 5V Output are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, (MAXM17904 and MAXM17905) 1.5% Feedback Accuracy compensation components, and inductor that operate over a wide input-voltage range. The modules oper- Up to 300mA Output-Current Internally Compensated ate from 4.5V to 24V input and deliver up to 300mA All Ceramic Capacitors output current. The MAXM17904 and MAXM17905 are fixed 3.3V and 5V output modules respectively. The High Efficiency MAXM17906 is an adjustable output (0.9V to 6.3V) Selectable PWM- or PFM-Mode of Operation module. The modules significantly reduce design Shutdown Current as Low as 2.2A (typ) complexity, manufacturing risks, and offer a true plug and Flexible Design play power/supply solution, reducing time-to-market. Internal Soft-Start and Prebias Startup The MAXM17904/MAXM17905/MAXM17906 modules Open-Drain Power Good Output (RESET Pin) employ peak-current-mode control architecture. To reduce Programmable EN/UVLO Threshold input inrush current, the modules offer a fixed 3.75ms Robust Operation soft-start time. Hiccup Overcurrent Protection The MAXM17904/MAXM17905/MAXM17906 modules Overtemperature Protection are available in a low profile, compact 10-pin, 2.6mm x -40C to +125C Ambient Operating Temperature/ 3mm x 1.5mm, uSLIC package. -40C to +150C Junction Temperature Rugged Applications Complies with CISPR22(EN55022) Class B Industrial Sensors and Encoders Conducted and Radiated Emissions 4-20mA Current-Loop Powered Sensors Passes Drop, Shock, and Vibration Standards: LDO Replacement JESD22-B103, B104, B111 HVAC and Building Control Ordering Information appears at end of data sheet.

Package Information PACKAGE TYPE: 10-PIN uSLIC Package Code M102A3+2 Outline Number 21-100094 Land Pattern Number 90-100027 THERMAL RESISTANCE, FOUR-LAYER BOARD (Note 2) Junction to Ambient ( ) 41.56 C/W JA For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Note 1: Junction temperature greater than +125C degrades operating lifetimes. Note 2: Package thermal resistance is measured on an evaluation board with natural convection.
