KA7552A/KA7553A  
SMPS Controller  
Features  
Description  
• Built-in drive circuits for direct connection power  
The KA7552A/KA7553A are switching power control IC  
for wide operating frequency range. The internal circuits  
include pulse by pulse current limiting, protection, on/off  
control by external trigger, low standby current, soft start,  
and high current totempole output for driving a POWER  
MOSFET. Maximum duty of the KA7552A is 70% and the  
KA7553A is 46%. When duty is maximum, the input  
threshold voltage of pin2 & pin8 are not same in KA7552A  
and KA7553A.  
MOSFET (l = ±1.5A)  
O
• Wide operating frequency range (5kHz ~ 600kHz)  
• Pulse by pulse over current limiting  
• Over load protection  
• On/off control by external trigger  
• Internal UVLO  
• Low standby current (typ. 90uA)  
• Soft start circuit
