Powersolve Unveils New DC-DC Switching Regulators for Distributed Power Systems

Powersolve released its PMQ7861 series of non-isolated 3A or 10W dc-dc switching regulators designed for battery or distributed power applications. The new regulators feature a wide 4.5 to 20Vdc input range and offer a 1.2 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% and a 380kHz switching frequency, customers can order the PMQ7861 series regulators in a very compact open PCB SIL format or in a SMD package.

Operating ambient temperature range is -25 to +70°C (derating above 55°C) and short circuit and over current protection are standard. Start up time is just 2mS typical and line and load regulation are both 2%.
