EVAL-LTC3313EV-A-Z

EVAL-LTC3313EV-A-Z is an evaluation board for evaluating the LTC3313 5V, 15A synchronous step-down silent switcher in 3mm × 3mm LQFN package. The LTC3313 is a compact, ultralow emission, high-efficiency, and high speed synchronous monolithic step-down switching regulator. The Silent Switcher technology optimizes fast-current loops and makes it easier to minimize electromagnetic interference (EMI) and electromagnetic compatibility (EMC) emissions. The minimum on-time of 35 ns typical enables high VIN to low VOUT conversion at a high frequency. The EVAL-LTC3313EV-A-Z runs in forced continuous mode with a 2MHz switching frequency (fSW); however, it can be configured to run at different switching frequencies or in pulse-skipping mode. The LTC3313 oscillator can also synchronize to an external clock using a MODE/SYNC turret, with the EVAL-LTC3313EV-A-Z default setup.

• Transient circuit included for load transient evaluation
• EMI filter included to reduce noise in EMI emission tests
• MODE pin pull-up option for pulse-skipping mode evaluation
