LTC3105EDD#PBF

Special Purpose Regulators Overview

The LTC3105EDD#PBF is a high-efficiency synchronous step-up DC/DC converter designed for energy harvesting applications. It operates from input voltages as low as 225mV, enabling startup from sources such as piezoelectric transducers or thermoelectric generators. The device integrates maximum power point tracking (MPPT) to optimize energy extraction. It provides a regulated output voltage and supports an output current of up to 400mA. The component is housed in a compact DFN-10 package.

Special Purpose Regulators Feature Summary

• Integrates maximum power point control for optimized energy harvesting
• Operates with ultra-low start-up voltage down to 225mV
• Synchronous rectification ensures high conversion efficiency
• Includes integrated LDO regulator for auxiliary power

Special Purpose Regulators Applications

• Piezoelectric energy harvesting systems
• Thermoelectric generator power supplies
• Low-voltage battery charging circuits
• Wireless sensor node power management

Special Purpose Regulators Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance when sourcing. Confirm the DFN-10 package dimensions against your PCB footprint requirements. Ensure the input source can provide sufficient current to meet the 400mA output demand during MPPT operation. Check for available demonstration boards like the DC1587A for initial circuit validation.

Special Purpose Regulators Selection Notes

Select this component when the energy source voltage is significantly lower than the required system rail. The integrated MPPT feature simplifies design by automatically adjusting the operating point. Consider the thermal performance of the DFN-10 package under continuous load conditions. Verify that the input source impedance matches the converter's optimal operating range for efficient power transfer.

Special Purpose Regulators Part Context

This part belongs to the LTC3105 family of micropower step-up converters. It is distinct from standard regulators due to its specialized MPPT functionality and ultra-low start-up capability. The EDD#PBF designation specifies the surface-mount DFN-10 package variant. It serves as a core power management IC for autonomous devices relying on ambient energy sources.
