Description
The 07CY-60T Series are isolated DC/DC converters that operate from a nominal 48V source. These units provide up to 60W of output power from a nominal 48V input. These units are designed to be highly efficient and low cost. Features include remote on/off, short circuit protection, over current protection, over temperature protection, input under voltage lockout, and output over voltage protection. These converters are provided in an industry standard eighth brick package.

Output Trim Equations
Equations for calculating the trim resistor (in kΩ) are shown below. The Trim Down resistor should be connected between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin and the Vout. Only one of the resistors should be used for any given application.
Vout
Rtrimdown =
511 − 10.22 delta
Module
Trim Rtrimdown GND
Rtrimup =
(100 + delta ) ⋅Vo ⋅ 5.11 − 626 − 10.22 1.225 ⋅ delta
Module
Vout Rtrimup Trim GND
Notes:
delta =
(Vo _ req − Vo ) × 100 [% ]

Vo_req=Desired (trimmed) output voltage [V]
Output voltage Vo=3.308V for 3.3V output; Vo=5.002V for 5.0V; Vo=12.007V for 12V output
