Overview
The LT8210EFE#TRPBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices, designed for high-voltage applications with input and output ranges up to 100V. It supports pass-thru, forced continuous conduction mode (CCM), pulse-skipping, and Burst Mode operations. The device features a switching frequency range of 80kHz to 400kHz and includes an external VCC LDO powered by the output or external rail. Key electrical specifications include a minimum input voltage of 2.8V, an output voltage range of 1V to 100V, and a quiescent current of 18µA in pass-thru mode. It offers precise current monitoring accuracy of ±3% and regulation accuracy of ±5% across the operating temperature range.
Feature Summary
- Pass-thru operation allows direct input-to-output transfer within a programmable window without switching noise or losses.
- Supports multiple operational modes including forced CCM, pulse-skipping, and Burst Mode for optimized light-load efficiency.
- Integrated 10V four-channel N-channel MOSFET gate drivers enable efficient control of external power switches.
- Features spread spectrum modulation to reduce electromagnetic interference during switching transitions.
Applications
- Automotive start-stop systems
- Emergency call systems
- Industrial and telecom infrastructure
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the E package corresponds to the 38-lead TSSOP form factor as defined in the official datasheet. Ensure compatibility with required thermal management solutions for the selected operating environment before finalizing procurement orders.
Selection Notes
Select this controller for designs requiring wide input voltage ranges up to 100V with high efficiency at light loads. Consider the pass-thru capability for applications needing low noise during specific voltage windows. Evaluate the need for external MOSFETs driven by the integrated gate drivers versus internal switch solutions available in other family members.
Part Context
This component belongs to the LT8210 series of buck-boost controllers manufactured by Analog Devices. It is part of a family offering various packages and pin configurations, such as the LT8210IFE variants. The device addresses power management needs in automotive and industrial sectors where robust voltage conversion and low standby currents are critical.
Replacement Considerations
LT8210EFE#PBF serves as the tube-packaged equivalent of this tape-and-reel component. Other variants like LT8210IFE#TRPBF offer different package options but share similar functional characteristics within the same product family.
