What are the key features of LTC3561AEDD#TRPBF?
- 1 A continuous output current with 2.5 V to 5.5 V input voltage range
- 4 MHz constant-frequency switching reduces output filter component size
- Adjustable output voltage from 0.8 V to 5 V covering a wide range of logic rails
- Current-mode control provides fast transient response and cycle-by-cycle overcurrent protection
- Compact leadless (DFN) package minimizes PCB footprint in space-constrained designs
What is LTC3561AEDD#TRPBF used for?
The LTC3561AEDD#TRPBF is ideal for point-of-load regulation in portable electronics, wearable devices, and IoT modules that run from single-cell lithium-ion or USB 5 V rails requiring a tightly regulated sub-1 V or 1.8 V supply. Its 4 MHz switching frequency allows tiny external inductors and capacitors, reducing overall solution size in multi-rail power trees. The adjustable 0.8 V to 5 V output range also suits FPGA core, DDR memory, and RF transceiver supply rails in compact communication modules.

Frequently Asked Questions
What input voltage range does the LTC3561AEDD#TRPBF support, and how does that suit lithium-ion battery applications?
The LTC3561AEDD#TRPBF accepts input voltages from 2.5 V to 5.5 V, which covers the full discharge range of a single-cell lithium-ion battery (approximately 2.7 V to 4.2 V) as well as USB 5 V rails. This broad range allows the converter to maintain a regulated output down to 0.8 V throughout the battery's usable discharge cycle without additional boost circuitry.
How does the 4 MHz switching frequency of the LTC3561AEDD#TRPBF reduce the size of external passive components?
At 4 MHz, the required inductance for a 1 A buck stage is typically 1 µH to 2.2 µH rather than the 10 µH or 22 µH needed at 400 kHz, and output capacitance can similarly shrink to a few microfarads. This results in a complete power solution that fits within a few square millimeters of PCB area, critical for wearable devices and wireless sensor nodes where every mm² counts.
Can the LTC3561AEDD#TRPBF generate both 1.8 V and 1.0 V core rails from a 3.3 V intermediate bus in a multi-rail FPGA power design?
The LTC3561AEDD#TRPBF's adjustable output range of 0.8 V to 5 V allows it to generate either a 1.0 V FPGA core rail or a 1.8 V I/O rail from a 2.5 V to 5.5 V input. Deploying two devices—one per rail—delivers up to 1 A per output at 4 MHz switching, with independent current-mode control loops providing stable, low-ripple regulation even under dynamic FPGA load transients.
