Regulators for battery or distributed power tasks

Powersolve's PMQ7861 series of non-isolated 3A or 10W DC/DC switching regulators is designed for battery or distributed power applications.

The new regulators feature a 4.5VDC to 20VDC input range and offer a 1.2VDC to 12VDC adjustable output (a 1.5V overhead voltage is required between input and output).

Features include input under-voltage lockout and positive logic remote on/off.

With efficiencies as high as 88 per cent and a 380kHz switching frequency, customers can order the PMQ7861 series of regulators in a compact open PCB SIL format or in an SMD package.

The operating ambient temperature range is -25C to +70C (de-rating above 55C) and short-circuit and over-current protection are standard.

The start-up time is 2mS typical and line and load regulation are both two per cent.
