KA3511BS  
Intelligent Voltage Mode PWM IC  
Features  
Description  
• Complete PWM control and house keeping circuitry  
• Few external components  
• Precision voltage reference trimmed to 2%  
• Dual output for push-pull operation  
The KA3511BS is a fixed-frequency improved-  
performance pulse-width modulation control cir-  
cuit with complete housekeeping circuitry for use  
in the secondary side of SMPS (Switched mode  
power supply). It contains various functions, which  
are precision voltage reference, over voltage pro-  
tection, under voltage protection, remote on/off  
control, power good signal generator and etc.  
• Each output TR for 200mA sink current  
• Variable duty cycle by dead time control  
• Soft start capability by using dead time control  
• Double pulse suppression logic  
• Over voltage protection for 3.3V / 5V / 12V  
• Under voltage protection for 3.3V / 5V / 12V  
• One more external input for various protection (PT)  
• Remote on/off control function (PS-ON)  
• Latch function controlled by remote and protection input  
• Power good signal generator with hysteresis  
OVP (Over voltage protection) section  
It has OVP functions for +3.3V,+5V,+12V and PT  
outputs. The circuit is made up of a comparator  
with four detecting inputs and without hysteresis  
voltage. Especially, PT (Pin18) is prepared for an  
extra OVP input or another protection signal.  
Precision reference section  
UVP (Under voltage protection) section  
The reference voltage trimmed to ± 2%  
(4.9V≤Vref≤5.1V)  
It also has UVP functions for +3.3V, +5V, +12V out-  
puts. The block is made up of a comparator with three  
detecting inputs and without hysteresis voltage.  
PG (Power good signal generator) section  
Power good signal generator is to monitor the volt-  
age level of power supply for safe operation of a  
microprocessor.  
KA3511BS requires few external components to  
accomplish a complete housekeeping circuits for  
SMPS.  
Remote on/off section  
Remote on/off section is used to control SMPS ex-  
ternally. If a high signal is supplied to the remote  
on/off input, PWM signal becomes a high state and  
all secondary outputs are grounded. The remote on/  
off signal is transferred with some on-delay and  
off-delay time of 8ms, 24ms respectively.
