The LTM4609MP is designed to deliver precision regulation in demanding environments in applications such as military, avionics, heavy industrial machinery, and harsh environment sensors. These uModule devices are backed by Linear Technology's rigorous reliability and quality test standards.

The LTM4609MP is a high voltage and high efficiency DC/DC system in a surface mount 15 mm x 15 mm x 2.8 mm LGA package. The device regulates an output voltage from a variable input voltage greater than, less than or equal to the output voltage.

The LTM4609MP operates from 4.5 VIN to 36 VIN, regulates an output voltage from 0.8 V to 34 V and can deliver an output power up to 100 W. Included in the uModule regulator is a synchronous buck-boost DC/DC controller, four N-channel MOSFETs, input and output bypass capacitors and compensation circuitry in a small plastic molded package. Only an inductor, feedback and sense resistors, and bulk capacitors are required to implement a low profile, compact and high efficiency design. Application examples are point-of-load and intermediate-bus regulation in networking, industrial and automotive systems and high-power battery-operated devices.

With the LTM4609MP's onboard proprietary 4-switch synchronous MOSFET design, the device achieves up to 98.3% efficiency in boost mode and up to 97.3% efficiency in buck mode (condition: VIN: 6.5 V to 36 V, VOUT: 30 V, IOUT: 2 A).
