UC1843B-D
Description
The UTC UC1842B-D/1843B-D 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 UC1842B-D and UC1843B-D are the under-voltage lockout thresholds.
Key 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
