Overview
The LC72344W and LC72345W are low-voltage
electronic tuning microcontrollers that include a DC-DC
converter, a PLL that operates up to 230 MHz, a 1/4 duty
1/2 bias LCD driver and other functions on chip. The
built-in DC-DC converter provided by these ICs can easily
implement a tuning system voltage generator circuit, and
furthermore, since the transistor required for the low-pass
filter is built in, these ICs can contribute to further end
product cost reductions. Additionally, the DC-DC
converter output voltage can be provided to other external
ICs, making these products optimal for low-voltage
portable audio equipment that includes a radio receiver.
