Figure 1. UCC3858 Typical application circuit.
APPLICATION INFORMATION (cont.)
* Pins 4, 9 and 14 need good bypassing to GND for noise immunity. Capacitors C2, C3 and C23 should each consist of a combination of ce-
ramic (0.47
μ
F) and tantalum (4.7
μ
F) capacitors for best results.
* * L1 can be fabricated with an Allied Signal Amorphous Core MP4510PFC, using a 100 turn (AWG 18) primary and 5 turn secondary. Alterna-
tively, a gapped Ferrite Choke can be used. (Coiltronics CTX-08-13679)
