Datasheet

Linear Technology has today announced the launch of a new 14V, 4A step-down µModule regulator in a 6.25 x 6.25 x 5.01mm BGA package. Including a few passive components, the LTM4624 fits within 1cm² on a single-sided PCB or within 0.5cm² on a double-sided PCB. The LTM4624, as with other µModule regulators, includes the DC-DC controller, power switches, inductor and compensation in a single package.

Operating from a 4V to 14V input supply, the LTM4624 offers a regulated output adjustable between 0.6V to 5.5V. This makes the new µModule regulator suited for communications, storage, industrial and medical system applications. The LTM4624 requires only two external ceramic capacitors (1206 case size) and a resistor (0603 or smaller case size) for operation.

Featuring a very low 5mV output ripple at full load during a 12VIN to 1.5VOUT conversion, the LTM4624 operates at a 1MHz typical switching frequency. The LTM4624 can operate from an input voltage as low as 2.375V with the addition of an external bias supply above 4V. Overcurrent and over-temperature fault protection are included in the regulator.

LTM4624 key features:

4A DC/DC Step-Down Solution in Less Than 1cm²,
Only Two Capacitors & One Resistor Required for a Complete Solution,
6.25 x 6.25 x 5.01mm BGA,
4V to 14V VIN Range,
VIN Range as Low as 2.375VIN with External Bias Supply,
Low 5mV Output Ripple at 1.5VOUT, 4A,
User Adjustable VOUT Between 0.6V to 5.5V.

The LTM4624 is available with guaranteed operation over the -40°C to +125°C internal temperature range. Available for immediate delivery from stock, pricing for the LTM4624 starts at $5.95 each for 1,000 piece quantities.
