INSTRUCTION MANUAL
CHVM3 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 sided metallic shield, with lower ripple and lower noise.

Specifications
Note1: The output voltage will be controlled by applying the Vcont voltage. Using an adjustable resistor or an
external voltage, voltage should be applied on the Vcont pin in order to control the output voltage.
When Vcont voltage=0V the output voltage (output residual voltage) should be less than 0.5% of
the max output voltage(I/O rated).
Note2: Details are subject to change for improvement, etc., without prior notice.
