Linear Technology has launched the LTM4624, a new 14V, 4A step-down µModule regulator in a 6.25 x 6.25 x 5.01mm BGA package which, including a few passive components, fits within 1cm2 on a single-sided PCB or 0.5cm2 double-sided.
The regulator includes the DC/DC controller, power switches, inductor and compensation in a single package and only two external ceramic capacitors (1206 case size) and a resistor (0603 or smaller case size) are required for operation.
The device operates from a 4V to 14V input supply, delivering a regulated output adjustable between 0.6V to 5.5V, ideal for applications in communications, storage, industrial, and medical systems.
The LTM4624 operates at a 1MHz typical switching frequency with a very low 5mV output ripple at full load during a 12VIN to 1.5VOUT conversion. With the addition of an external bias supply above 4V, the LTM4624 can operate from an input voltage as low as 2.375V. Overcurrent and over-temperature fault protection are included in the regulator.
The LTM4624 is available with guaranteed operation over the -40°C to +125°C internal temperature range.
