•
High Density Isolated Standby Bias Supplies  
DC-to-DC Converters  
•
Wide Operating Input Voltage Range from 12 V  
to 100 V, 105-V Surge.  
DESCRIPTION  
The UCC25230 is a highly integrated PWM converter  
operating as an isolated forward flyback. It has  
high-side and low-side power switches integrated and  
the control circuit with all key converter functions  
included. The power stage requires only one- or  
multiple winding coupled inductor and output  
capacitors for the complete solution. Voltage-mode  
feed-forward control with external compensation  
allows optimal output filter selection over wide input  
voltage range. The UCC25230 has fixed frequency  
set internally at 380 kHz. It also includes input voltage  
UVLO and OVLO comparators with hysteresis and  
input-good, open-collector output signal which can be  
used to enable PWM controllers.

Other features include internal soft start and  
cycle-by-cycle current protection. Measured efficiency  
of isolated converter over input voltage and output  
current ranges are shown in Figure 2.
