UC2844/45

LINEAR INTEGRATED CIRCUIT

HIGH PERFORMANCE

CURRENT MODE PWM

CONTROLLERS

DESCRIPTION

The UTC UC2844/2845 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 UC2844 and UC2845 are the maximum

duty cycle ranges and under-voltage lockout thresholds. The

UC2844 ideally suited to off-line applications with UVLO thresholds

of 16V_(ON)and 10V_(OFF), and UC2845 has UVLO thresholds of

8.5V_(ON)and 7.6V_(OFF)for lower voltage applications.

FEATURES

* Operation output switching frequency up to 500 kHz

* Output deadtime adjustable from 50% to 70%

* 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
