Key Features
- 2 A charge current from input voltages up to 32 V enables direct connection to solar panels and high-voltage adapters without pre-regulation
- Tracking topology maximizes efficiency by keeping power dissipation low across a wide 4 V to 32 V input range
- 77-pin LGA μModule package integrates power FETs, magnetics, and control circuitry for minimal external component count
Applications
The LTM8062EV#PBF is designed for portable and energy-harvesting applications where a Li-Ion or Li-Polymer battery is charged from variable high-voltage sources such as 6 V to 24 V solar panels or AC adapters. Its tracking architecture and 32 V maximum input rating suit it for outdoor IoT nodes, handheld instruments, and ruggedized field equipment needing efficient 2 A battery charging without a separate voltage pre-regulator.

Frequently Asked Questions
What input voltage range and maximum charge current does the LTM8062EV#PBF support?
The LTM8062EV#PBF accepts input voltages from approximately 4 V up to 32 V and delivers up to 2 A of charge current to Li-Ion or Li-Polymer battery cells. This wide 32 V input tolerance allows direct connection to 12 V and 24 V solar panels as well as standard 5 V USB or 19 V laptop-style AC adapters without additional voltage conversion stages.
How does the tracking topology of the LTM8062EV#PBF improve efficiency in solar-powered charging systems?
The LTM8062EV#PBF uses a tracking architecture that dynamically adjusts its internal regulation to maintain minimum headroom above the battery voltage, rather than dissipating the full input-to-battery voltage difference. This reduces power dissipation significantly when the input is 24 V and the battery is at 3.7 V, achieving effective efficiency improvements of 30 to 50% over non-tracking linear chargers at the same 2 A charge rate.
What does the 77-pin LGA package integrate, and how does this reduce external BOM complexity?
The LTM8062EV#PBF's 77-pin LGA package integrates the charge control IC, power MOSFETs, and all required passive components including the charge current sense resistor and compensation network. This μModule integration reduces the external BOM to just a few capacitors and resistors for setting the 2 A charge current and input threshold, compared to 20 or more external components needed for a discrete Li-Ion charger design.
When should a designer choose the LTM8062EV#PBF over a conventional 5 V-input USB Li-Ion charger IC?
When the available charging source exceeds 5.5 V — such as a 12 V or 24 V solar panel, automotive accessory port, or industrial 24 V supply — a conventional USB charger IC would require a pre-regulator, adding cost and loss. The LTM8062EV#PBF directly accepts up to 32 V input, eliminating that pre-regulation stage and reducing total solution size by approximately 40% while maintaining 2 A charge current capability.
