The LM2735XMYEVAL evaluation board converts 3V to 5.5V input to 12V output for up to 500mA load current using the LM2735Y 520kHz DC to DC switching converter in the 8Pin MSOP PowerPAD package. This is a two layer board using the bottom layer as a ground plane. It provides all the active functions to provide local DC to DC conversion with fast transient response and accurate regulation in the smallest PCB area. Switching frequency is internally set to 520kHz, allowing the use of extremely small surface mount inductor and chip capacitors while providing efficiencies up to 90%. Current mode control and internal compensation provide ease of use, minimal component count and high performance regulation over a wide range of operating conditions. External shutdown features an ultra low standby current of 80nA ideal for portable applications.
