A new 14V, 4A step-down µModule regulator from Linear Technology has been released. The device is a 6.25 by 6.25 by 5.01mm BGA which, including a few passive components, fits within 1cm2 on a single-sided PCB or 0.5cm2 double-sided.
The LTM4624 includes a DC/DC controller, power switches, inductor and compensation in a single package. It delivers a regulated output adjustable between 0.6V to 5.5V and is ideal for applications in telecom, datacom, networking and industrial equipment, medical diagnostic equipment, military and aircraft systems.
Operation is at a 1MHz typical switching frequency with a low 5mV output ripple at full load during a 12VIN to 1.5VOUT conversion. The device can operate from an input voltage as low as 2.375V. Overcurrent and overtemperature fault protection are included in the regulator.
