Linear Technology LTC3568

The LTC3568’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The LTC3568 can be configured for automatic power saving Burst Mode operation to reduce gate charge losses when the load current drops below the level required for continuous operation. For reduced noise and RF interference, the SYNC/MODE pin can be configured to skip pulses or provide forced continuous operation.
