INSTRUCTION MANUAL
CHVM2 Series
TDK­Lambda
<Page>
The CHVM series is an adjustable output voltage type mid­high voltage DC­DC converter.
Output voltage can be controlled using an external voltage or external adjustable resistor. The CHVM series has
adopted a 5 side metallic shield, with farther low ripple and low noise.

Specifications
Note1: The output voltage can be controlled by impressing the Vcont voltage. Using an adjustable resistor or an
external voltage,voltage should be impressed on the Vcont pin in order to control the output voltage.
When Vcont voltage=0V the output voltage(residual output voltage)
should be less than 0.5% of the max output voltage (at Input/Output rating).
Note2: Details are subject to change for improvement, etc., without prior notice.
