LTC7803: 40 V, Low IQ Synchronous Step-Down Controller
The single output LTC7803 showcase the latest technology in switching regulator step-down DC/DC controllers. All products feature up to 3 MHz operating switching frequency and very low IQ, along with PassThru/100% duty cycle capability and spread spectrum frequency modulation.
40 V Low IQ, 3 MHz Synchronous Step-Down Controller with Spread Spectrum
Key Features and Benefits
- PassThru/100% duty cycle capability allows output voltages to stay in regulation longer when powered from a discharging battery
- Very low IQ increases battery run-time during standby mode
- High power onboard gate drives drive external MOSFETs with low switching loss for increased efficiency
Applications
- Automotive: Auto connect and Sensing
- Industrial Automation: Connected motion and robotics
- Instrumentation and Measurement: ATE
- Aerospace and Defense: Radar
Evaluation Board
- The LTC7803 can be evaluated with the DC2834A.
