UC1851

UC2851

UC3851

Programmable, Off-Line, PWM Controller

FEATURES

DESCRIPTION

•

All Control, Driving, Monitoring, and Protection

Functions Included

The UC1851 family of PWM controllers are optimized for off-

line primary side control. These devices include a high current

totem pole output stage and a toggle flip-flop for absolute 50%

duty cycle limiting. In all other respects this line of controllers is

pin for pin compatible with the UC1841 series. Inclusion of all

major housekeeping functions in these high performance con-

trollers makes them ideal for use in cost sensitive applications.

•

Low-Current Off Line Start Circuit

Voltage Feed Forward or Current Mode Control

High Current Totem Pole Output

50% Absolute Max Duty Cycle

Important features of these controllers include low current

start-up, linear feed-forward for constant volt-second operation,

and compatibility with both voltage or current mode control. In

addition, these devices include a programmable start thresh-

old, as well as programmable over-voltage, under-voltage, and

over current fault thresholds. The fault latch on these devices

can be configured for automatic restart, or latched off response

to a fault.

PWM Latch for Single Pulse Per Period

Pulse-by-Pulse Current Limiting plus Shutdown

for Over-Current Fault

•

No Start-Up or Shutdown Transients

Slow Turn-On Both Initially and After Fault

Shutdown

These devices are packaged in 18-pin plastic or ceramic dual-

in-line packages, or for surface mount applications, a 20 Pin

PLCC. The UC1851 is characterized for -55°C to +125°C op-

eration while the UC2851 and UC3851 are designed for -40°C

to +85°C and 0°C to +70°C, respectively.

•

Shutdown Upon Over or Under Voltage Sensing

Latch Off or Continuous Retry After Fault

1% Reference Accuracy

500kHz Operation
