Integrated 4V-60V, 150mA, Himalaya uSLIC Power Module DC-DC Converter with 50mA Linear Regulator

Highly Integrated Industrial PMIC Enables Small Solution Size with Integrated Inductor

Product Details

The Himalaya series of voltage-regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM17710–MAXM17726 family of dual output regulators integrate a high efficiency 150mA synchronous step-down DC-DC converter and a high PSRR, low noise, 50mA linear regulator into uSLIC™ power modules. The modules operate from a wide input voltage range of 4V to 60V. The step-down converter and linear regulator can deliver output currents up to 150mA and 50mA, respectively. MAXM17710–MAXM17714 modules offer fixed 3.3V output from the DC-DC converter. MAXM17715–MAXM17720 modules offer fixed 5V output from the DC-DC converter. MAXM17721–MAXM17726 modules offer adjustable output voltage from the DC-DC converter. The output of the DC-DC converter serves as the input to the linear regulator. The linear regulators offer fixed output voltages between 1.2V and 3.3V in different modules. Refer to the Ordering Information for a complete list of part numbers. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power supply solution, reducing time to market.

The modules employ peak current mode control architecture for step-down converters. To reduce input inrush current, the modules offer a fixed soft-start of 5.1ms (typ) for the step-down converter and 1.1ms (typ) for the linear regulator.

The modules are available in a low profile, compact 10-pin (2.6mm x 3mm x 1.5mm) uSLIC package.

Description

The MAXM17712/MAXM17720/MAXM17724 evaluation kits (EV kit) provide a proven design to evaluate the performance of MAXM17712/MAXM17720/MAXM17724 modules. Each of these modules operates over a wide input range from 5.5V to 60V, and features an integrated 150mA step-down converter and 50mA linear regulator. The modules are configured to demonstrate optimum performance and component sizes in this EV kit.

MAXM17712 delivers up to 150mA from the 3.3V fixed output step-down converter, and up to 50mA from the 1.8V fixed output linear regulator. The step-down converter is configured to operate at 375kHz switching frequency, over a 5.5V to 60V input range.

MAXM17720 delivers up to 150mA from the 5V fixed output step-down converter, and up to 50mA from the 3.3V fixed output linear regulator. The step-down converter is configured to operate at 570kHz switching frequency, over an 8.4V to 60V input range.

MAXM17724 is configured to deliver up to 150mA from the adjustable output step-down converter programmed to 5V, and up to 50mA from the 2.5V fixed output linear regulator. The step-down converter is configured to operate at 570kHz switching frequency, over an 8.4V to 60V input range.

The EV kits feature provisions for selecting mode of operation (PWM or PFM), synchronization to an external clock source, enable/disable, and UVLO settings. The MAXM17710–MAXM17726 module family data sheet provides a complete description of the parts and should be read in conjunction with this data sheet prior to operating the EV kits.
