Burst Mode is a registered trademark of Linear Technology Corporation. All other trademarks are the property of their respective owners. A high efficiency mA, 0. Current mode topology is used for fast transient response and good loop stability. Innovative design techniques along with a new high volt- age process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by employing Burst Mode operation at low currents, utilizing the output to bias the internal circuitry, and by using a supply boost capacitor to fully saturate the power switch.
Burst Mode operation can be defeated by a logic high signal on the SYNC pin which results in lower light load ripple at the expense of light load efficiency. Patented circuitry maintains peak switch current over the full duty cycle range. External synchronization can be imple- mented by driving the SYNC pin with logic-level inputs. A single capacitor from the C SS pin to the output provides a controlled output voltage ramp soft-start.
