SNVS276I April 2004 – February 2019 LM2743
PRODUCTION DATA.
The following section provides a step-by-step design guide of a voltage-mode synchronous buck converter using the LM2743. This design converts 3.3 V (VIN) to 1.2 V (VOUT) at a maximum load of 4 A, with an efficiency of 89% and a switching frequency of 300 kHz. The same procedures can be followed to create many other designs with varying input voltages, output voltages, and load currents.
