MAXM17710MAXM17726 Integrated 4V60V, 150mA, Himalaya uSLIC Power Module DC-DC Converter with 50mA Linear Regulator General Description Benefits and Features The Himalaya series of voltage-regulator ICs and power Easy to Use modules enable cooler, smaller, and simpler power-sup- Wide 4V to 60V Input Step-Down Converter ply solutions. The MAXM17710MAXM17726 family of Adjustable and Fixed Output Voltage Modules Internal Inductor and Compensation dual output regulators integrate a high efficiency 150mA synchronous step-down DC-DC converter and a high Up to 150mA Output Current from a Step-Down Converter PSRR, low noise, 50mA linear regulator into uSLIC power modules. The modules operate from a wide input 1.3% Accuracy for Linear Regulator Output and 2% FB Accuracy for Step-Down Converter voltage range of 4V to 60V. The step-down converter and All Ceramic Capacitors, Compact Layout linear regulator can deliver output currents up to 150mA Built-In 50mA high PSRR Linear Voltage Regulator and 50mA, respectively. MAXM17710MAXM17714 mod- with Different Output Voltage Options ules offer fixed 3.3V output from the DC-DC converter. MAXM17715MAXM17720 modules offer fixed 5V output High Efficiency from the DC-DC converter. MAXM17721MAXM17726 Selectable PWM or PFM mode operation modules offer adjustable output voltage from the DC-DC PFM Enables Enhanced Light-Load Efficiency converter. The output of the DC-DC converter serves 2.5A Shutdown Current as the input to the linear regulator. The linear regulators 70A No-Load Supply Current offer fixed output voltages between 1.2V and 3.3V in dif- Flexible Design ferent modules. Refer to the Ordering Information for a Internal Soft-Start and Prebias Startup complete list of part numbers. The modules significantly 350kHz to 2.2MHz Adjustable Switching Frequency reduce design complexity, manufacturing risks, and offer with External Synchronization for Step-Down a true plug-and-play power supply solution, reducing Converters time to market.
