Description

The DC1901A is a demonstration board featuring LTC3639EMSE device. The LTC3639EMSE is a high efficiency step down DC to DC regulator with internal high side and synchronous power switches that draws only 12µA typical DC supply current while maintaining a regulated output voltage at no load. The IC operates in a high efficiency burst mode operation and includes internal high and low side power MOSFETs. The board will accept input voltage between 4V and 150V and provide jumper selected output voltages of 1.8V, 3.3V, 5V and an option for additional voltages. The IC includes internal soft start and a provision for increasing soft start time. Included on the board is an ON/OFF jumper that can also be configured as a precision undervoltage lockout. Additional PC pads are included for programming current limit to optimize efficiency and for reducing output voltage ripple and reducing component size. A terminal is included to allow multiple boards to be paralleled for higher output current.
Maximum output current of 100mA
87.3% efficiency
Typical output ripple of 66mVpp
Synchronous operation for highest efficiency
Internal high side and low side power MOSFETs
No compensation required
Low dropout operation, 100% duty cycle
Internal or external soft start
Few external components required
Programmable input overvoltage lockout
Be careful when testing with high voltage. High voltage can result in an electric shock if care is not taken.
