1) R_a = 249kΩ
2) C_a = 15pF 0402 MLCC capacitor.
3) Then R_b is given as:
R ^{= 1.501x105 Ω}
b _{VOUT − 0.603}
V_OUT can be programmed over the range of
0.603V to V_IN-0.4V.
4) Do not connect the sense line.
NOTE: Stability cannot be assured if these
guidelines are not followed.
For 700mA operation, use the following
component values:
