1 / 6 page ©2004 Fairchild Semiconductor Corporation www.fairchildsemi.com Rev. 1.0.2 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 Description 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. 8-DIP 1 Internal Block Diagram 8 7 1 6 5 4 3 2 CS CT RT VCC OUTPUT GND IS(+) FB 0.56 ~ 0.42V 10uA 7V PWM 2.4V 1.9V O.C.P 0.24V 4.3K OFF 3.6V 2.8V OSC UVLO R S Q BIAS (4V) + _ + - - - _ + + - + - KA7552A/KA7553A SMPS Controller |
