- AN-1747, 3A LM20k Reference Design Using for LM20143 High Efficiency 3A Synchronous Buck Converter. The LM20143 is a full-featured family of high performance 3A synchronous buck converter. This device is tailored to operate over an input voltage range of 2.95 V to 5.5 V and each can be optimized to meet many different performance requirements. The LM20143 is except the frequency of the device can be varied from 460 kHz to 1.5 MHz with an external resistor. This gives the power supply designer the flexibility to trade-off inductor size and efficiency
