Introduction
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(0N) and 10V(0FF), and UC2845 has UVLO thresholds of 8.5V(0N) and 7.6V(0FF) 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
- Pb-free plating product number: UC2844L/UC2845L
