Pricing/Samples/Availability
The constant-current-limit is programmable on the UCx832 to allow higher peak current
during the on-time of the pass device. With duty-ratio control, high initial load demands and
short circuit protection may both be accommodated without extra heat sinking or foldback
current limiting. Additionally, if the timer pin is grounded, the duty-ratio timer is disabled,
and the IC operates in constant-voltage/constant-current regulating mode.
These IC’s include a 2 Volt (±1%) reference, error amplifier, UVLO, and a high current
driver that has both source and sink outputs, allowing the use of either NPN or PNP external
pass transistors. Safe operation is assured by the inclusion of under-voltage lockout (UVLO)
and thermal shutdown.
The UC1833 family includes the basic functions of this design in a low-cost, 8-pin mini-dip
package, while the UC1832 series provides added versatility with the availability of 14 pins.
Packaging options include plastic (N suffix), or ceramic (J suffix). Specified operating
temperature ranges are: commercial (0°C to 70°C), order UC3832/3 (N or J); industrial (–
25°C to 85°C), order UC2832/3 (N or J); and military (–55°C to 125°C), order UC1832/3J.
Surface mount packaging is also available.
