ET- KA384x
Current Mode PWM Controller
Description
The KA384x are fixed frequency
current mode PWM controller. They are
specially designed for off-line and DC to DC
converter applications with a minimal
external components.
Internally implemented circuits include
a trimmed oscillator for precise duty cycle
control, a temperature compensated
reference, high gain error amplifier, current
sensing comparator, and a high current
totem pole output ideally suited for driving a
power MOSFET. Protection circuitry
includes built under voltage lockout and
current limiting.
Features
¾ Low Star-up and Operating Current
¾ High Current Totem Pole Output
¾ Under Voltage Lockout With Hysteresis
¾ Operating Frequency Up to 500KHz
Applications
¾ Switching Mode Power Supplies
¾ Power Converters
