This condition will shorten the off time at frequencies >= 30KHz , and is magnified at high temperature. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a nondarlington configuration is used, the follow ing output drive condition is recommended: Forced Bata of output switch: Ic output / ( Ic driver – 7mA*) >= 10 * The 100ohm resistor in the emitter of the dr iver div ide requires about 7mA before the output sw itch conduc ts. 2/10 Version: A07 T S3 4 0 6 3 Dc to Dc Converter Controller Electrical Characteristics Curve 3/10 Version: A07 T S3 4 0 6 3 Dc to Dc Converter Controller Typical Application Circuit Test Line R egulation Load R egulation Output Ripple Efficiency Output Ripple w ith Optional Filter Conditi ons VIN= 8V~16V, Io= 175mA VIN = 12V, Io= 75mA to 175mA VIN =12V, Io= 175mA VIN =12V, Io= 175mA VIN =12V, Io= 175mA Results 30mV = ± 0.05% 10mV = ± 0.017% 400mVpp 87.7% 40mVpp Fi gure 7.

Vripple(p-p): Desired peak- to-peak output ripple voltage. in pr actice, the calculated capacitor value will need to be increased due to its equivalent series resis tance and board layout. The ripple voltage should be kept to a low value since it will direc tly affect the line and load regulation. 7/10 Version: A07 T S3 4 0 6 3 Dc to Dc Converter Controller SOP-8 Mechanical Drawing DIM A B C D F G K M P R SOP-8 DIMEN SION MILLIMETER S INCH ES MIN MAX MIN MAX. 4.80 5.00 0.189 0.196 3.80 4.00 0.150 0.157 1.35 1.75 0.054 0.068 0.35 0.49 0.014 0.019 0.40 1.25 0.016 0.049 1.27BSC 0.05BSC 0.10 0.25 0.004 0.009 0º 7º 0º 7º 5.80 6.20 0.229 0.244 0.25 0.50 0.010 0.019 Marking Diagram Y = Year Code M = Month C ode (A=Jan, B =Feb, C=Mar, D=Apl, E=May, F=Jun, G=Jul, H=Aug, I=Sep, J=Oc t, K=Nov , L=Dec) L = Lo t C ode 8/10 Version: A07 T S3 4 0 6 3 Dc to Dc Converter Controller DIP-8 Mechanical Drawing DIP-8 D IMENS ION DIM A B C D G J K L M MILLIMETERS MIN 9.07 6.22 3.18 0.35 0.29 3.25 7.75 MA X 9.32 6.48 4.45 0.55 0.31 3.35 8.00 10 o INCHES MIN 0.357 0.245 0.125 0.019 0.011 0.128 0.305 MA X 0.367 0.255 0.135 0.020 0.012 0.132 0.315 10 o 2.54 (typ) 0.10 (typ) Marking Diagram Y = Year Code M = Month C ode (A=Jan, B =Feb, C=Mar, D=Apl, E=May, F=Jun, G=Jul, H=Aug, I=Sep, J=Oc t, K=Nov , L=Dec) L = Lo t C ode 9/10 Version: A07 T S3 4 0 6 3 Dc to Dc Converter Controller Notice Specifications of the produc ts displayed herein are s ubject to change without notice.
