UNISONIC TECHNOLOGIES CO., LTD  
UC2843B  
LINEAR INTEGRATED CIRCUIT  
HIGH-PERFORMANCE  
CURRENT-MODE PWM  
CONTROLLERS  
DESCRIPTION  
The UTC UC2843B provides off-line or DC-DC  
fixed-frequency current-mode control design with minimum  
external components. Internally-implemented circuits include an  
under-voltage lockout (UVLO) and a precision reference with  
accuracy at the error amplifier input. The UTC UC2843B also  
contain internal circuits which include a pulse width modulation  
(PWM) comparator providing current-limit control, logic ensuring  
latched operation, and a totem-pole output stage designed to  
source or sink high-peak current. The output stage is low when it  
is in off-state condition and suitable for N-channel MOSFETs  
driving.  
The UTC UC2843B also has following advantages: the  
start-up current lower than 0.5mA while the oscillator discharge  
current is specified to 8.3mA (Typ.). In UVLO conditions, the  
output has a maximum saturation voltage of 1.2V when sinking  
10mA@VCC = 5V.  
The typical UVLO threshold of the UTC UC2843B is 8.4V  
(on) and 7.6V (off) and can operate to duty cycles approximately  
100%.  
FEATURES  
* Current mode operation:500 kHz  
* Automatic feed-forward compensation  
* Low start-up current value<0.5mA  
* Latching PWM for cycle-by-cycle current limiting  
* Trimmed oscillator discharge current  
* Internally trimmed reference with UVLO  
* High-current totem-pole output UVLO with hysteresis  
* Double-pulse suppression
