Key Features
- Integrated USB power manager with dual buck, boost, and buck-boost converters providing 6 regulated channels from a single Li-ion or USB input
- Adjustable threshold control enabling programmable battery charge termination and output voltage across all converter channels for flexible system power architecture
- 38-pin QFN (PQCC-N38) package with exposed pad for efficient thermal dissipation in slim portable devices
Applications
The LTC3586EUFE-2#PBF is designed for portable consumer electronics, handheld instruments, and wireless devices that require multi-rail power management from a USB 5 V input or a single-cell Li-ion battery. Its integrated buck-boost topology maintains a regulated output even when the battery voltage crosses the output setpoint during discharge, ideal for 3.3 V and 1.8 V rail generation in smartphones and IoT wearables. The six-channel architecture eliminates multiple discrete converters, reducing total solution size and BOM cost in space-constrained designs.

Frequently Asked Questions
How many DC-DC converter channels does the LTC3586EUFE-2#PBF integrate, and what topologies are included?
The LTC3586EUFE-2#PBF integrates 6 converter channels: 2 synchronous buck converters, 1 boost converter, and 1 buck-boost converter, all managed by a single USB power manager controller. This combination supports generating multiple regulated rails—such as 1.8 V, 3.3 V, and 5 V—from a 3.0 V to 4.2 V Li-ion battery or a 5 V USB source.
Why is a buck-boost topology in the LTC3586EUFE-2#PBF critical for single-cell Li-ion battery designs?
A single-cell Li-ion battery discharges from 4.2 V down to 3.0 V, crossing the typical 3.3 V regulated output setpoint mid-discharge. The buck-boost channel in the LTC3586EUFE-2#PBF seamlessly transitions between buck and boost modes at this crossover, maintaining a regulated 3.3 V output across the full battery state-of-charge without glitches, which prevents microcontroller resets or data loss during deep discharge.
What package does the LTC3586EUFE-2#PBF use and how does it affect thermal management?
The LTC3586EUFE-2#PBF uses a 38-pin QFN (PQCC-N38) package measuring approximately 5 mm × 7 mm with an exposed thermal pad on the bottom. The thermal pad connects directly to the PCB copper ground plane, allowing conduction of several watts of dissipated power into a standard 2-layer board without requiring an external heatsink in most portable application scenarios.
