ECB and LCD Display Bias Supply with Accurate
Output Voltage and Temperature Compensation
Table 1. Recommended Inductors
Table 2. Recommended Capacitor Values
*Use a low-leakage capacitor.
Proper PC board layout minimizes output ripple and
increases efficiency. For best results, use a ground
plane, minimize the space between C1, C2, and GND
of the MAX1729, and place the inductor as close to LX
and IN as possible. For an example of proper PC board
layout, refer to the MAX1729 Evaluation Kit.
