Planar Transformers For National Semiconductor
LM5030 Controller IC
Less than 10 mm high, Coilcraft’s planar transformers are
ideal for use in high-current telecom power supply appli-
cations that require high efficiency in a low-profile package.
These transformers are designed specifically to perform
with the National Semiconductor LM5030 Push-Pull Cur-
rent Mode PWM Controller. They provide three different
output ratings to suit a variety of applications All offer
1500 Vrms primary to secondary isolation.
Coilcraft’s A9785-B, A0153-A and B0414-A are output
chokes and include an extra winding for auxiliary voltage
supply. Our MSS6132-103 functions as the input filter
choke in the same circuit. Refer to separate data sheets
for additional information on these parts.
