Product Description
- 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.
- 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
