LINEAR INTEGRATED CIRCUIT

HIGH PERFORMANCE

CURRENT MODE PWM

CONTROLLERS

DESCRIPTION

The UTC UC2842A/2843A are high performance fixed

frequency current mode controllers that specifically designed for

Off-Line and DC to DC converter applications with minimal external

parts count.

The differences between UC2842A and UC2843A are the

under-voltage lockout thresholds. The UC2842A ideally suited to

off-line applications with UVLO thresholds of 16V_(ON)and 10V_(OFF)

and UC2843A has UVLO thresholds of 8.4V_(ON)and 7.6V_(OFF)for

lower voltage applications.



FEATURES

* Operation output switching frequency up to 500 kHz

* Automatic feed forward compensation

* Latching PWM for cycle-by-cycle current limiting

* High current totem pole output

* Internally trimmed reference with under voltage lockout

* UVLO with hysteresis

* Low startup and operating current
