C1,C2 Stabilization capacitors of Vcc and VREF.
VR1 It is decided considering a load capacity of VREF.
(A load capacity is approximately 5mA.)
Recommended value is around 10k
.
C3,D1 They are for the soft start function. A time constant is decided considering VR1.
Cagc This capacitor is for stabilization of AGC. A larger capacitor improves a stability of the
system, however a system response is degraded.
Recommended value is around 1μF.
Cosc This capacitor is for a saw wave generation. Recommended value is around 1000pF.
R1,R2,R3,R4 They are for a gain setting of the error Amp. R2 should be several k
to dozens of k
C4,C5 to set a voltage gain 20dB to 40 dB at f = 1kHz, so that the feed back loop is stable.
When the voltage gain is too low, it causes jitter.
Recommended values of C4, C5 and R1 are ;
C4 = dozens of pF to several hundreds pF
C5 = several thousands pF to tens of thousands pF
R1 = dozens of k
to several hundreds k
.
*Annotation:Connect 7pin and 8pin terminal to GND when don't use under voltage protection (UVP).
