DC DC Switching Controllers datasheet and documents for LTC3835EDHC-1#PBF
DC DC Switching Controllers Overview
The LTC3835EDHC-1#PBF is a high-performance synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 36V and supports output voltages from 0.8V to 10V. The device drives all N-channel synchronous power MOSFETs using a constant-frequency current mode architecture, allowing for phase-lockable frequencies up to 650kHz. It is housed in a compact 16-lead DFN package.
DC DC Switching Controllers Feature Summary
- Drives all N-channel synchronous power MOSFET stage for high efficiency
- Constant-frequency current mode architecture allows phase-lockable frequency
- Integrated bootstrap diode eliminates external component requirements
DC DC Switching Controllers Applications
- High efficiency 12V to 1.8V step-down converters
- High efficiency 3.3V to 5A step-down converters
- High efficiency 5V to 5A step-down converters
- High efficiency 1.2V to 5A step-down converters
DC DC Switching Controllers Procurement Notes
Verify the specific suffix #PBF indicates tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact electrical specifications required for your design, as variations exist within the LTC3835 family. Cross-reference with official datasheets for pinout and thermal characteristics.
DC DC Switching Controllers Selection Notes
Select this controller when designing buck converters requiring drive for external N-channel MOSFETs rather than integrated switches. Consider the 650kHz maximum switching frequency for balancing size and efficiency. Ensure the application input voltage stays within the 4V to 36V range and that the output voltage configuration aligns with the 0.8V to 10V capability.
DC DC Switching Controllers Part Context
This component belongs to the LTC3835 series of low IQ synchronous step-down controllers. It is designed for applications demanding high efficiency and compact solution sizes. The EDHC-1 variant specifically refers to the 16-lead DFN package type, distinguishing it from other package options like SSOP or QFN available in the broader product line.
DC DC Switching Controllers Replacement Considerations
Direct replacements include other parts within the LTC3835 family such as LTC3835EGN-1#PBF or LTC3835IDHC-1#PBF, depending on the required package and temperature grade. Verify compatibility regarding switching frequency limits and output voltage ranges before substitution.
