The voltage and current amplifiers have a 3MHz gain
bandwidth product to satisfy high performance system
requirements. The internal current sense amplifier per-
mits the use of a low value current sense resistor, mini-
mizing power loss. The oscillator frequency is fixed
internally at 100kHz, 200kHz, or 400kHz, depending
upon the option selected. The foldback circuit reduces
the converter short circuit current limit to 50% of its nomi-
nal value when the converter is short circuited. The gate
driver is a 4
totem pole output stage capable of driving
an external MOSFET.
This device is available in 20-pin dual in-line and surface
mount packages. The UCC3830-x is specified for opera-
tion from 0°C to 70°C.
