LC72345W Datasheet (Sanyo Semicon Device) - Low-Voltage ETR Controller

LC72345W, Low-Voltage ETR Controller

Ordering number : ENN6171 CMOS IC LC72344W, 72345W Low-Voltage ETR Controller with On-Chip DC-DC Converter 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-pas
