KEC KIA494AP
The KIA494AP/AF incorporates on a single monolithic chip all the functions required in the construction of a pulse-widthmodulation control circuit. Designed primarily for power supply control, this device offers the systems engineer the flexibility to tailor the power supply control circuitry to a specific application. The KIA494AP/AF contains two error amplifiers, an on-chip adjustable oscillator, a dead-tme control(DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision requlator, and output-control circuits.| Part No. | KIA494AP |
