August 20, 2013 – Linear Technology Korea (CEO Hong Sa-gwak) announced the launch of a 14V, 4A step-down µModule® (micromodule) regulator in a 6.25 x 6.25 x 5.01mm BGA package. With required passive components integrated into the product, it fits perfectly into a single-sided PCB footprint of less than 1cm² or a double-sided PCB of 0.5cm². Like other µModule regulators, the LTM4624 integrates a DC/DC controller, power switches, inductor, and compensation function into a single package. Only two external ceramic capacitors (1206 case size) and one resistor (0603 or smaller case size) are required for operation. The LTM4624 operates from 4V to 14V input supply and provides adjustable output between 0.6V and 5.5V, making it ideal for applications in communications, storage, industrial and medical systems.

The LTM4624 exhibits very low 5mV output ripple characteristics during power conversion under conditions of 12VIN, 1.5VOUT, maximum load, and 1MHz (typical) switching frequency. By adding an external bias supply of 4V or higher, the LTM4624 can operate at input voltages as low as 2.375V. Overcurrent and overtemperature error protection functions are built into the regulator.

The LTM4624 is available with guaranteed operation over an internal temperature range of -40°C to +125°C. The µModule regulator is available immediately. Pricing is set at $5.95 per unit based on a quantity of 1,000 units. For more information, visit www.linear.com/product/LTM4624참조.
