Overview
The LT8570HDD-1#PBF is a PWM DC/DC converter manufactured by Analog Devices Inc., featuring an integrated 65V power switch. It supports Boost, SEPIC, and Inverting topologies with an adjustable output voltage range from 1.204 V to 65 V. The device operates with a switching frequency of 1.5 MHz and provides an output current of 200 mA. It functions within an input voltage range of 2.55 V to 40 V and maintains a static current of 1.2 mA. The component is housed in an 8-DFN package and operates between -40°C and +125°C.
Feature Summary
- Configurable as a boost, SEPIC, or inverting DC/DC converter
- Integrated 65V power switch for high-voltage applications
- Adjustable output voltage up to 65 V
Applications
- Inverting converters generating negative outputs from positive inputs
- Boost converters for stepping up lower input voltages
- SEPIC converters for isolated or non-isolated voltage regulation
Procurement Notes
Verify availability status directly with the manufacturer or authorized distributors, as supply may be limited. Confirm that the specific suffix matches the required pinout and thermal characteristics. Ensure compliance with RoHS directives if applicable to your assembly process. Cross-reference the datasheet revision to confirm electrical parameters match your design requirements before finalizing procurement.
Selection Notes
Select this component when a compact solution for high-voltage conversion is required. The 1.5 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 200 mA output current limit against your load requirements. The DFN-8 package offers a small footprint suitable for space-constrained designs.
Part Context
This part belongs to the LT8570 family of PWM DC/DC converters. The family includes variants with different packages and switching frequencies, such as the LT8570EDD-1#PBF which supports a wider frequency range. The LT8570 series is designed for applications requiring flexible topology configuration and robust performance under varying input conditions.
Replacement Considerations
Check for LT8570EDD-1#PBF for similar functionality with potentially different frequency options. Verify LT8570EMS8E-1#PBF for MSOP-8 packaging compatibility. Ensure any substitute maintains the 65V switch rating and supported topologies.
