The KA7552A is a PWM Controller programmable frequency up to 600kHz. The KA7552A is 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 totem pole output for driving a POWER MOSFET. When duty is maximum, the input threshold voltage of pin2 and pin8 are not same in KA7552A.
● Built-in drive circuits for direct connection POWER MOSFET (lO = ±1.5A)
● Wide operating frequency range (5 to 600kHz)
● Pulse by pulse over-current limiting
● Overload protection
● On/off control by external trigger
● Internal UVLO
● Low standby current (typical 90uA)
● Soft start circuit
