Dongguang Debuts DG1842/43/44/45 Controllers

Beijing Dongguang Microelectronics Co. Ltd. (China) announced its new DG1842/43/44/45 single-end, isolated PWM controllers, which offer a complete solution for isolating dc/dc fixed-frequency control circuits.

The DG1842 and DG1844 feature threshold values of 16V (on) and 10V (off). The duty ratio is about 100 percent for the DG1842 and DG1843, while it is up to 55 percent for both the DG1844 and DG1845.

The DG1842 controller offers maximum absolute ratings of 30V and ±1A output. Power consumption is 1W at 25 degrees C maximum ambient temperature.
