LT3434 - High Voltage 3A, 200kHz Step-Down Switching Regulator with 100μA Quiescent Current - Linear Technology（凌力尔特）

功能描述
The LT3434 is a 200kHz monolithic buck switching regulator that accepts input voltages up to 60V. A high efficiency 3A, 0.1? switch is included on the die along with all the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability.

Innovative design techniques integrated in a new high voltage 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. Patented circuitry maintains peak switch current over the full duty cycle range.* Shutdown reduces input supply current to less than 1μA. External synchronization can be implemented by driving the SYNC pin with logic-level inputs. A single capacitor from the CSS pin to the output provides a controlled output voltage ramp (soft-start). The device also has a power good flag with a programmable threshold and time-out, and thermal shutdown protection.

The LT3434 is available in a 16-pin TSSOP package with exposed pad leadframe for low thermal resistance.
