Hi-Voltage Input High Reliability DC-DC Converters
The high input voltage series DC-DC converters have two outputs, i.e. single output and dual output. The input voltage of single-output variety is generally 24~32V, the max. output power is 10W and the output voltage can reach 900V. The input voltage of dual-output variety is 18V, the max. output power is 25W and the output voltage is 1500V and 4500V, respectively.
The first stage is voltage regulation stage, the second stage is input-output isolation stage. Output voltage produce error amplifying signal by error amplifier. This signal is use for control the duty ratio of PWM waveform thus controlling the output voltage of the whole module.
These series products has module circuits structure with PCB surface mounted technology, inside the products, using conductivity material for embedding and aluminum baseboard for cooling.
