TS3410 1A / 1.5MHz Synchronous Buck Converter 4/7 Version: A08 Inductor Selection For most designs, the TS3410 operates with inductors of 1µH to 4.7µH. Low inductance values are physically smaller but require faster switching, which results in some efficiency loss. The inductor value can be derived from the following equation: Table 1: Resistor Select for Output Voltage Setting VOUT R2 R1 1.2V 300K 300K 1.5V 300K 450K 1.8V 300K 600K 2.5V 300K 950K
