H822

The H822 is a DC/DC converter with galvanic isolation, a hybrid integrated circuit made in Romania by ICCE (CCSIT-CE) and listed in the Agenda radioelectronistului (2nd edition, 1989) in group 8.2 „Convertoare c.c./c.c.” (DC/DC converters) of the family „Surse de putere” (power supplies) [1].

The two editions disagree on the voltages of the H 822. The 2nd edition (1989) describes it exactly like the H 821 above it, „Convertor c.c./c.c. cu separare galvanică (24V/5V)” [1], while the 1st edition (1983) lists the H 821 as „Convertor c.c./c.c. (24V/5V)” and the H 822 as „Convertor c.c./c.c. (24V/±15V)” [2]. The 2nd edition thus gives two different codes the same description; the 1st edition makes the H 822 a converter with a ±15 V output.

The table gives no parameters or drawing. In it, the first two digits of every code repeat the numbers of its family and group (here 8.2) [1].
