DESCRIPTION:
The ASD150QV Series of products are open frame, high density, dc/dc converters designed for use in distributed power architectures and may, in many
cases, be used as fit and function replacements for industry standard half brick
modules with a 40% space savings. Synchronous Rectification enables these
power supplies to produce up to 150W of high efficiency power in an 1/4th brick
(2.3in. x 1.45in. x 0.47in. ) package.

NOTES
1.Measured before Input Filter
2.Scope measurement should be made using a BNC connector with 1uF
and 10uF aluminum electrolytic capacitor across output. Scope set to
read at 20MHz bandwidth.
3. 25%-50%-75% load, 0.1A/uS
4. The Cold Start condition is a uniform converter temperature of -40°C
after thermal stabilization. The Hot Start condition for start up is a uniform converter temperature of 65°C after thermal stabilization.
All specifications are typical at nominal input, full load, and 25DegC unless
otherwise noted

Where:
∆ % = [(V nominal-V desired)/Vnominal] x 100%
Example: For Vout = 2.97, use Rtrim-down = 40.2 kOhms
For Vout = 3.63, use Rtrim-up = 168 kOhms
