Features Built-in Drive Circuits for Direct Connection POWER
MOSFET (lO= ±1.5A) 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
DescriptionThe 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 thresh-
old voltage of pin2 & pin8 are not same in KA7552A and
KA7553A.
