LTC3802EUH#PBF General Description
The LTC3802 is a dual switching regulator controller optimized for high efficiency step-down conversion from input voltages between 3V to 30V. The controller uses a leading edge modulation scheme to allow extremely low duty cycle operation. The constant frequency voltage mode controller allows a phase-lockable frequency between 330kHz and 750kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages 180° out of phase. The synchronous buck architecture automatically shifts to Burst Mode operation as the output load decreases, ensuring maximum efficiency over a wide range of load currents.
Features
- Wide VIN Range: 3V to 30V Operation with Line Feedforward Compensation
- Leading Edge Modulation Architecture for Extremely Low Duty Cycle Operation
- Phase-Lockable Fixed Frequency: 330kHz to 750kHz
- Two 180° Out-of-Phase Controllers
- Fast Programmable Power-Up/-Down Tracking
- Programmable Current Limit Without External Current Sense Resistor
- Optional Burst Mode® Operation at Light Load
- ±1% 0.6V Voltage Reference
- External N-Channel MOSFET Architecture
- Low Shutdown Current: <100µA
- Overvoltage Protection and PGOOD Flag
- Small 28-Lead SSOP and 32-Lead QFN Packages
Application
- Notebook and Palmtop Computers
- Portable Instruments
- Battery-Operated Digital Devices
- DC Power Distribution Systems
