DESCRIPTION
The LTC®3543 is a high efficiency monolithic synchronous current mode buck
regulator.
The switching frequency is internally set at 2.25MHz, allowing the use of
small surface mount inductors and capacitors. In PLL mode, the LTC3543 can
acquire frequencies between 1MHz and 3MHz. Also, the LTC3543 has spread
spectrum capability providing a lower noise regulated output, as well as low
noise at the input.
