DC3109A
Overview
Features and Benefits
- DC3109A evaluation board
- Transient circuit included for load-transient evaluation
- EMI filter included to reduce noise in EMI emission tests
Product Details
Demonstration circuit DC3109A is a 2 MHz, 2.5 V to 5.5 V input, 1.2 V/1.75 A output buck regulator, featuring the LTC3306, 1.75A, synchronous step-down regulator in 1.6 mm x 1 mm WLCSP. The LTC3306 is a small size, high efficiency, low noise monolithic synchronous step-down DC-DC converter. Low minimum on-time of 22 ns enables high VIN to low VOUT conversion at high frequency. The LTC3306 supports fixed output voltages ranging from 0.5 V to 3.65 V.
The demo circuit features the adjustable version of LTC3306. Output voltage is adjusted to 1.2 V with external feedback resistors. The DC3109A-A is set up to run in Burst Mode with LTC3306A. The DC3109A-C is set up to run in forced continuous mode with LTC3306C. The high precision PGOOD signal shows the status of the output voltage.
The DC3109A also has an EMI filter to reduce the conducted EMI. This EMI filter can be included by applying the input voltage at the VIN EMI terminal. The EMI performance of the board is shown in the EMI Test Results section.
Full specifications on the LTC3306 are available in the LTC3306 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the DC3109A evaluation board. The LTC3306 is assembled in a 6-ball, 1.6 mm x 1 mm, 0.5 mm pitch WLCSP package.
