Overview
The LT8570IDD#TRPBF is a PWM DC/DC converter from Analog Devices Inc. featuring an integrated 65V power switch. It supports boost, SEPIC, and inverting topologies with an input voltage range of 2.55 V to 40 V. The output voltage is adjustable from 1.204 V to 65 V, supporting up to 400 mA output current. Operating at a fixed 1.5 MHz switching frequency, it offers low quiescent current of 1 uA and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Configurable as a boost, SEPIC, or inverting converter topology
- Integrated 65V power switch for high-voltage applications
- Low static current consumption of 1 uA
- Fixed 1.5 MHz switching frequency
Applications
- Generating negative voltages from positive inputs (inverting)
- Boosting low input voltages to higher levels
- SEPIC configurations for wide input voltage ranges
- Industrial control systems requiring isolated or inverted rails
Procurement Notes
Verify the suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the specific IDD variant matches the required thermal performance and package dimensions for your PCB layout. Ensure compatibility with the 1.5 MHz fixed frequency operation during system design validation.
Selection Notes
Select this part for applications requiring a compact solution with a 65V switch rating. The 1.5 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 400 mA switch current limit when designing for maximum load requirements.
Part Context
This component belongs to the LT8570 family of single-switch DC/DC converters. It shares core architecture with variants like LT8570EDD#PBF but differs in packaging and shipping format. The family is designed for versatile power conversion needs in space-constrained environments.
Replacement Considerations
LT8570EDD#PBF is a pin-compatible alternative in a tube package. LT8570EMS8E-1#PBF offers similar functionality in an MSOP-8 package. Verify thermal characteristics and switching frequency consistency before substitution.
