HIGH-PERFORMANCE CURRENT-MODE PWM CONTROLLERS

The  UTC  UC2842B  provides  off-line  or  DC-DCfixed-frequency current-mode control design with minimumexternal components. Internally-implemented circuits include anunder-voltage lockout (UVLO) and a precision reference withaccuracy at the error amplifier input. The UTC UC2842B alsocontain interna Current mode operation:500 kHz Low start-up current value<0.5mA Latching PWM for cycle-by-cycle current limiting Trimmed oscillator discharge current Automatic feed-forward compensation Internally trimmed reference with UVLO High-current totem-pole output UVLO with hysteresis Double-pulse suppressio;
