MAXM15462/MAXM15463/ 4.5V to 42V, 300mA Himalaya uSLIC MAXM15464 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 42V Input solutions. The MAXM15462/MAXM15463/MAXM15464 Adjustable 0.9V to 5V Output Fixed 3.3V and 5V Output (MAXM15463 and are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, MAXM15464) 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 42V input and deliver up to 300mA All Ceramic Capacitors output current. The MAXM15463 and MAXM15464 are fixed 3.3V and 5V output modules respectively. The High Efficiency MAXM15462 is an adjustable output (0.9V to 5V) mod- Selectable PWM- or PFM-Mode of Operation ule. The modules significantly reduce design complexity, Shutdown Current as Low as 2.2A (typ) manufacturing risks, and offer a true plug and play power/ Flexible Design supply solution, reducing time-to-market. Internal Soft-Start and Prebias Startup The MAXM15462/3/4 modules employ peak-current- Open-Drain Power Good Output (RESET Pin) mode control architecture. To reduce input inrush current, Programmable EN/UVLO Threshold the modules offer a fixed 4.1ms soft-start time. Robust Operation The MAXM15462/3/4 modules are available in a low pro- Hiccup Overcurrent Protection file, compact 10-pin, 2.6mm 3mm 1.5mm, uSLIC Overtemperature Protection package. -40C to +125C Ambient Operating Temperature/ -40C to +150C Junction Temperature Applications Rugged Industrial Sensors and Encoders Complies with CISPR22(EN55022) Class B 4-20mA Current-Loop Powered Sensors Conducted and Radiated Emissions 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.
