UC1517
UC3517
Although component values can be best optimized experimentally, good starting values speed development. For this design,
start with: where:
RT CT = 3 LW/RW LW is winding inductance,
C1 = C2 = LW IR/RW
R1 = R2 = 2.9 TMIN/C1
RW is winding resistance,
IR is rated winding current, and
TMIN is minimum step period expected.
