Product Overview
LT1956 is a monolithic buck switching regulator with an input voltage capability upto 60V. A current mode architecture provides fast transient response and good loop stability. Special design techniques and a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch. Patented circuitry maintains peak switch current over the full duty cycle range. It is widely used in application such as high voltage, industrial and automotive, portable computers, battery-powered systems, battery chargers, distributed power systems etc.
- Wide input range is 5.5V to 60V
- Peak switch current is 2A typ
- Saturating switch design is 0.2 ohm
- Constant switching frequency is 500kHz typ
- Effective supply current is 2.5mA
- Shutdown current is 25µA typ
- Easily synchronizable
- Cycle-by-cycle current limiting
- Operating temperature is -40°C to 125°C, feedback reference is 1.2V typ
- Packaging style is 16-lead plastic TSSOP
