DC491A, Demo Board based on LTC1923EUH TEC Temperature Controller, 1.0-MHz Switching Frequency, 2.7-5.5V Input

DC491A, Demonstration Circuit DC491 features the LTC1923EUH thermoelectric cooler controller. The LTC1923EUH comes in a small 32-lead QFN package (5mm by 5mm). Since the switching frequency of the circuit is 1MHz, small size inductors and capacitors are used as output filters
