small size, Adjustable output voltage type high voltage power supply
0.2W Mid-high voltage DC-DC converter
0V to 100V, 0V to 200V BYH Series
The BYH series is an ultra small type mid-high voltage DC-DC converter which has stored 0 to 100V and 0 to 200V in a 24pin-IC.
Using the latest SMT (surface mount technology), the high voltage technology is now 1/3 to 1/4 of the original product.
■ Features
・Achieved 24pin-IC size
・5 sided metallic shield
・Output voltage 0 to 100V and 0 to 200・Low ripple noise of 10mVp-p
・Output capacity 0.2W
・Over current protection
・Bar in tests 100% conducted
・Adjustable voltage with external voltage
・Worlds ultra small size, device achieve・Isolation withhold between P-S, DC250V
・Low cost
・High reliability and long life

Note 1: The output voltage is controlled by the Vcont voltage being impressed. Connect an external voltage to impress to the
the Vcont pin to control the output voltage. When Vcont voltage =0V, the output voltage (output residual voltage) must be
within 0.5% of the max output voltage (when input/output is rated)
