DC397A - LT1930AES5/LT1931AES5 Demo Board | 3 Circuits: Boost/SEPIC/Inverter: 5Vin to 12Vout1@250mA, 10V-16Vin to 12Vout2@250mA, 12Vin to -12Vout3@250mA
Demonstration circuit 397 is a multipurpose DC/DC switching regulator using the LT1930A and LT1931A voltage regulators in a SOT-23 package. The demo board offers three separate DC/DC converters for different applications needs. The boost circuit is designed to convert a 5V input to 12V output at 250mA maximum load. The SEPIC circuit generates a constant 12V/250mA (max load) output with a 10V~16V variable input. The inverter circuit is de-signed for applications requiring negative 12V/250mA (max load) from a positive 12V input. All three circuits are designed to demonstrate fast switching frequency (2.2MHz), an internal 36V/1A switch, wide input range, and small circuit size.
