KA7553A controller equivalent, smps controller.
* Built-in drive circuits for direct connection power MOSFET (lO = ±1.5A)
* Wide operating frequency range (5kHz ~ 600kHz)
* Pulse by pulse over current limit.
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 to.
