UC2842B/2843B HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS
■The UTC UC2842B/2843B 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 UC2842B and UC2843B are the under-voltage lockout thresholds. The UC2842B ideally suited to off-line applications with UVLO thresholds of 16V (ON) and 10V (OFF), and UC2843B 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
