AP3842/3/4/5  
High Performance Current Mode PWM Controller  
„ Features  
„ General Description  
• Optimized for Off-Line and DC to DC Converters  
• Low Start-Up Current (≦0.5mA)  
The AP3842/3/4/5 family of control ICs provides the  
necessary features to implement off-line or DC to  
DC fixed frequency current mode control schemes  
with a minimal external parts count. Internally  
implemented circuits include under voltage lockout  
featuring start-up current less than 0.5 mA, a  
precision reference trimmed for accuracy at the  
error amp input, logic to insure latched operation, a  
PWM comparator which also provides current limit  
control, and a totem pole output stage designed to  
source or sink high peak current. The output stage,  
suitable for driving N-Channel MOSFETs, is low in  
the off-state.  
• Automatic Feed Forward Compensation  
• Pulse-by-Pulse Current Limiting  
• Enhanced Load Response Characteristics  
• Under-Voltage Lockout (UVLO) with Hysteresis  
• Double Pulse Suppression  
• High Current Totem Pole Output  
• Internally Trimmed Bandgap Reference  
• Current Mode Operation to 500KHZ  
• Low Ro Error Amplifier  
„ Pin Connections  
PDIP-8L, SOP-8L  
Top View  
Differences between members of this family are the  
under-voltage lockout thresholds and maximum  
duty cycle ranges. The AP3842 and AP3844 have  
UVLO thresholds of 16V(on) and 10V(off), ideally  
suited for off-line applications. The corresponding  
thresholds for the AP3843 and AP3845 are 8.5V  
and 7.6V. The AP3842 and AP3843 can operate to  
duty cycles approaching 100%. A range of the zero  
to < 50% is obtained by the AP3844 and AP3845  
by the addition of an internal toggle flip flop which  
blanks the output off every other clock cycle.
