5A, 20VIN Step-Down µModule Regulator's Entire Solution Fits within 0.5cm²

Dec 17 2014 - MILPITAS, CA
  • Linear Technology launched the LTM4625, a 5A, 20VIN step-down µModule® (micromodule) regulator in a 6.25mm × 6.25mm × 5.01mm BGA package which, with a few passive components, fits into 0.5cm2 on a double-sided PCB. Like other µModule regulators, the LTM4625 includes the DC/DC controller, power switches, inductor and compensation components in a single package. Only two external ceramic capacitors (1206 case size) and a resistor (0603 case size) are required for operation. The LTM4625 operates from a 4V to 20V input supply, delivering a regulated output adjustable between 0.6V to 5.5V with ±1.5% accuracy over line, load and temperature.

    The LTM4625 operates at a user adjustable switching frequency from 800kHz to 4MHz or can be synchronized to an external clock from 700kHz to over 1.3MHz. The module also provides a clock out signal at the same frequency with selectable phase shift (90°, 120° or 180°), useful when current sharing multiple LTM4625 modules for higher output current. With the addition of an external bias supply above 4V, the LTM4625 can operate from an input voltage as low as 2.375V. Output overvoltage, overcurrent and overtemperature fault protection are included in the regulator.

    The LTM4625 is available with guaranteed operation over the –40°C to 125°C internal temperature range. The µModule regulator is available for immediate delivery from stock, priced starting at $6.45 each for 1,000 piece quantities. For more information, visit www.linear.com/product/ltm4625.
