KA7553A Description

***emi: PWM Controller programmable frequency upto 600khz

***et: DC DC Cntrlr Single-OUT 8-Pin PDIP W Rail

***ser: Supervisory Circuits SMPS Controller

***rchild Semiconductor: 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.
