ANALOG DEVICES DC397A

DC397A demonstration circuit is a multipurpose DC/DC switching regulator using the LT1930A and LT1931A, the industry’s fastest and highest power voltage regulator 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 to 16V variable input. The inverter circuit is designed 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. These circuits are designed for space-conscious low profile applications such as cellular phones, palm top computers, digital cameras, and LCD displays.
