Tiny step down regulator fits in 1cm<sup>2</sup> package
Available in a tiny 6.25 x 6.25 x 5.01mm BGA package, the LTM4624 from Linear Technology is designed to fit within 1cm<sup>2</sup> on a single sided pcb or 0.5cm<sup>2</sup> double sided.
The 14V, 4A step down µModule regulator features a dc/dc converter, power switches, inductor and compensation in a single package. Only two external ceramic capacitors (1206 case size) and a resistor (0603 or smaller case size) are required for operation.
The LTM4624 operates from a 4 to 14V input supply, delivering a regulated output adjustable between 0.6 to 5.5V, making it suitable for applications in communications, storage, industrial and medical systems.
In addition, the device operates at a 1MHz typical switching frequency with a low 5mV output ripple at full load during a 12VIN to 1.5VOUT conversion.
With the addition of an external bias supply above 4V, Linear says the LTM4624 can operate from an input voltage as low as 2.375V. Overcurrent and overtemperature fault protection are included as standard.
