General Description
Key Specifications
◼ Operating Power Supply Voltage Range:
VCC Pin: 8.9 V to 26.0 V
This series of PWM-type DC/DC converters for AC/DC
supplies the optimum system for all products in which
an outlet is present. It is compatible with both insulated
and non-insulated, and various types of low-power
consumption converters can be easily designed.
The built-in 730 V startup circuit contributes to low
power dissipation. A highly flexible power supply design
is achieved by externally installing a current detection
resistor for switching. Because of the use of current
mode control, the current is limited every cycle,
providing excellent performance in bandwidth and
excessive response. The switching frequency is fixed at
100 kHz. When turned light load, the frequency is
reduced to achieve high efficiency. Built-in frequency
hopping function contributes to low EMI. Built-in 730 V
switching MOSFET enables easy designing.
