MAXM17630/MAXM17631/ 4.5V to 36V, 1A Himalaya uSLIC MAXM17632 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 36V Input solutions. The MAXM17630/MAXM17631/MAXM17632 Adjustable 0.9V to 12V Output (MAXM17632) Fixed 3.3V and 5V output versions (MAXM17630 are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, and MAXM17631) 400kHz to 2.2MHz Adjustable Frequency with compensation components and inductor that operate over a wide input-voltage range. The modules operate External Clock Synchronization 1.2% Feedback Accuracy from 4.5V to 36V and deliver up to 1A output current. Up to 1A Output Current The MAXM17630 and MAXM17631 are fixed 3.3V and Internally Compensated 5V output modules, respectively. The MAXM17632 is an All Ceramic Capacitors adjustable output (0.9V to 12V) module. The modules sig- nificantly reduce design complexity, manufacturing risks, High Efficiency and offer a true plug-and-play power-supply solution, Selectable PWM-, PFM- or DCM-Mode reducing time-to-market. Built-in compensation across of Operation the output-voltage range eliminates the need for external Auxiliary Bootstrap Supply (EXTVCC) for Improved compensation components. Efficiency Shutdown Current as Low as 2.8A (typ) These modules feature peak-current-mode control architecture. The modules can be operated in pulse- Flexible Design width modulation (PWM), or pulse-frequency modu- Adjustable and Monotonic Startup with Prebiased lation (PFM), or discontinuous-conduction mode Output Voltage (DCM) to enable high efficiency under light-load Built-In Output-Voltage Monitoring with RESET Pin conditions. Programmable EN/UVLO Threshold The feedback-voltage regulation accuracy over -40C Robust Operation to +125C for the module family is 1.2%. These power Hiccup-Mode Overload Protection modules are available in a low profile, compact 16-pin, Overtemperature Protection 3mm x 3mm x 1.75mm, uSLIC package. Simulation -40C to +125C Ambient Operating Temperature/ Models are available. -40C to +150C Junction Temperature Rugged Applications Complies with CISPR22(EN55022) Class B Industrial Control Power Supplies Conducted and Radiated Emissions General Purpose Point-of-Load Passes Drop, Shock, and Vibration Standards: JESD22-B103, B104, B111 Distributed Supply Regulation Base Station Power Supplies High Voltage Single-Board Systems Programmable Logic Controller Ordering Information appears at end of data sheet. uSLIC is a trademark of Maxim Integrated Products, Inc. 19-100596 Rev 1 10/19MAXM17630/MAXM17631/ 4.5V to 36V, 1A Himalaya uSLIC MAXM17632 Step-Down Power Module Typical Application Circuit C5 0.1F LX BST V VIN OUT OUT V IN 7V TO 36V 5V/1A C1 C4 4.7F 22F EN/UVLO FB MAXM17631 RESET EXTVCC MODE/SYNC SS V CC PGND EP RT SGND C2 C3 R1 15k 2.2F 5600pF fSW: 1250kHz C1: MURATA 4.7F/X7R/50V/1206 (GRM31CR71H475KA12) C4: MURATA 22F/X7R/25V/1210 (GRM32ER71E226KE15) C5 0.1F LX BST V IN OUT V V OUT IN 4.5V TO 36V 3.3V/1A C1 R4 R2 C4 4.7F 3.32M 229k 22F EN/UVLO FB R5 R3 MAXM17632 RESET EXTVCC 1.05M 88.7k MODE/SYNC SS V CC PGND EP RT SGND C2 C3 R1 5600pF 2.2F 21.5k f : 900kHz SW C1: MURATA 4.7F/X7R/50V/1206 (GRM31CR71H475KA12) C4: MURATA 22F/X7R/25V/1210 (GRM32ER71E226KE15) Maxim Integrated 2 www.maximintegrated.com
