Powerline has a new range of compact 10W DC/DC convertors in the industry standard package size of 1.25 x 0.8 x 0.4in - a power density of 25W/in3.

Powerline has a new range of compact 10W DC/DC convertors in the industry standard package size of 1.25 x 0.8 x 0.4in - a power density of 25W/in3.

The new UM3300 Series, which can be operated over a 2:1 input voltage range (18-36V for the nominal 24V input and 36-75V for the 48V input), offer high efficiency levels up to 82%, and produce a 5V DC output with a maximum current rating of 2A.

Voltage accuracy is +/-2% maximum, and ripple and noise are within 100mV peak-to-peak at 20MHz.

Line and load regulation are +/-0.2 and +/-0.5% maximum, respectively.

Switching frequency is 400kHz, and operating temperature range is from -25 to +100C with cooling by free-air convection.
