Sanyo Electric LC72344W
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.ABSOLUTE MAXIMUM RATINGS
