Linear released 36VIN, 600mA µModule step down regulator in 6.25x11.25 mm BGA

Linear Technology Corporation has introduced a 5µA quiescent current DC/DC step down µModule regulator 'LTM8029'. This device is capable of delivering up to 600mA.

This device is suitable for applications such as avionics, heavy industrial equipment, battery stack energy storage and factory automation and robotics.

Features of LTM8029

1. Input range: 4.5VIN to 36VIN (40Vmax)

2. Output range: 1.2V to 18V

3. 5µA quiescent current at 12VIN to 3.3VOUT

4. Dropout voltage: 0.6V at 600mA

5. Adjustable switching frequency: 200kHz to 2.2MHz

6. 36VIN, 600mA, µModule step down regulator

7. Efficiency of operation for 3.3VOUT, at 600mA from 5VIN, 12VIN, and 24VIN is 84%, 79% and 75%, respectively.

8. Rise in junction temperature is minimal at 17°C, when converting from 36VIN to 3.3VOUT at full current of 600mA.

9. In addition to positive-to-positive, the LTM8029 can be used to regulate a negative output voltage.

10. The LTM8029 includes the inductor, power switches, DC/DC controller and additional circuitry in a small 6.25 x 11.25 x 3.42 mm BGA package.

Pricing starts at $6.60 each for 1,000-piece quantities.
