Introduction
The LT1776 is a wide input range, high efficiency Buck (step-down) switching regulator. The monolithic die includes all oscillator, control and protection circuitry. The part can accept input voltages as high as 60V and contains an output switch rated at 700mA peak current. Current mode control delivers excellent dynamic input supply rejection and short-circuit protection.
The LT1776 contains several features to enhance efficiency. The internal control circuitry is normally powered via the VCC pin, thereby minimizing power drawn directly from the VIN supply. The action of the LT1776 switch circuitry is also load dependent. At medium to high loads, the output switch circuitry maintains fast rise time for good efficiency. At light loads, rise time is deliberately reduced to avoid pulse skipping behavior.
The available SO-8 package and 200kHz switching frequency allow for minimal PC board area requirements.
Features
- Wide Input Range: 7.4V to 40V
- Tolerates Input Transients to 60V
- 700mA Peak Switch Rating
- Adaptive Switch Drive Maintains Efficiency at High Load Without Pulse Skipping at Light Load
- True Current Mode Control
- 200kHz Fixed Operating Frequency
- Synchronized to 400kHz
- Low Supply Current in Shutdown: 30μA
- Available in 8- Pin SO and PDIP Packages
Applications
- Automotive DC/DC Converters
- Cellular Phone Battery Charger Accessories
- IEEE 1394 Step- Down Converters
