DC to DC Controllers
LTC7804HUD#PBF
The LTC7804 is a 40 V, Low IQ, 3 MHz synchronous boost controller can deliver up to 10A with 97% efficiency, which reduces power loss, increases efficiency, and minimizes board space
Analog DevicesLTC7804: 40 V Low IQ, 3 MHz Synchronous Boost Controller
The LTC7804 is a high performance synchronous boost DC-to-DC switching regulator controller.
Key Features and Benefits
- • Synchronous boost results in higher current and efficiency results in a smaller solution size
- • 100% duty cycle and PassThru mode eliminates switching loss in preboost applications
- • Spread spectrum frequency modulation reduces EMI
Applications
- • Automotive: preboost for powering infotainment systems in start-stop applications
- • Instrumentation: electronic test and measurement equipment
- • Healthcare: medical and life science
- • Aerospace and Defense: avionics
Evaluation Board
The LTC7804 can be evaluated with the DC2846A.
