KA7552A/KA7553A
SMPS Controller
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% an...
