5.4A, 36V µModule Buck-Boost Regulator

MILPITAS, CA - September 8, 2015 - Linear Technology Corporation introduces the LTM8054, a 36VIN (40Vmax) 5.4A µModule® (micromodule) regulator in small 11.25mm x 15mm x 3.42mm BGA package. The LTM8054 regulates an output voltage equal to, greater or less than the input voltage. This enables a regulated output voltage even if either or both input and output voltages vary greatly as the device seamlessly transitions between buck and boost functions. The device includes the inductor, DC/DC regulator, MOSFETs and the supporting components. The LTM8054 regulates an output voltage between 1.2V and 36V, from 5V to 36V input supply in three operating modes of buck (step-down), boost (step-up) and buck-boost (VIN approximates VOUT).

The LTM8054 includes a 4-switch buck-boost topology to maximize efficiency: 92% 24VIN, 12VOUT (buck) and 94% 36VIN, 24VOUT. Transition between the modes of operation is automatic, making the LTM8054 a simple and compact DC/DC regulator solution for a wide range of applications such as industrial controls, automotive, solar and high power battery-supplied systems.

The LTM8054 has input and output current limit and monitoring functions. This is ideal for applications that require constant current operation, such as LED drives, battery chargers, fan control and thermoelectric cooling controllers. Moreover, the device enables load sharing operation from various input sources. The switching frequency is adjustable by an external single resister from 100kHz to 800kHz and it can be synchronized to an external clock from 200kHz to 700kHz.

The LTM8054 operates from -40°C to 125°C and -55°C to 125°C. 1,000-piece pricing starts at $15.95 each. For more information, visit www.linear.com/product/LTM8054.
