DC2105A-B

DC2105A-B demonstration circuit is a 500mA output DC/DC power supply. This is a board featuring LTC3630 with 4 to 65V input range. The LTC3630 operates in a high-efficiency Burst Mode® operation and includes internal high and low side switches. The board provides jumper-selected output voltages of 1.8V, 3.3V, 5V and an option for additional voltages. LTC3630 has 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 the current limit to optimize efficiency and for reducing output voltage ripple and reducing component size. A terminal (FBO) is available to allow multiple boards to be paralleled for increasing output current. Output voltage between 800mV and VIN can be programmed using optional resistors, although higher voltage output capacitors will be required.

• 500mA maximum output current at VIN = 20V, VOUT = 5V
• 75mVP-P typical output voltage ripple at VIN = 20V, VOUT = 5V
