What are the key features of TPS65266RHBT?
- Triple-output synchronous buck topology delivers 3 A on channel 1 and 2 A each on channels 2 and 3 from a single 2.7 V–6.5 V input supply
- Current-mode PWM control with peak current limit of 3.7 A on outputs 2 and 3 provides built-in short-circuit protection and fast load transient response
- Compact 32-pad QFN package integrates three complete power stages to replace multiple discrete regulators and reduce total solution footprint
What is TPS65266RHBT used for?
TPS65266RHBT is designed for multi-rail power management in portable consumer electronics, tablets, and embedded single-board computers that derive three low-voltage rails from a single 5 V or 3.7 V lithium battery bus. Its three synchronous buck converters eliminate the need for three separate regulator ICs, reducing the component count and PCB area required for core, I/O, and memory supply rails. The 2.7 V minimum input also makes it suitable for Li-ion applications where the input voltage can fall below 3 V during heavy discharge.

Frequently Asked Questions
What are the individual output current ratings for each channel of TPS65266RHBT?
TPS65266RHBT provides three independent output channels: channel 1 supports up to 3 A, while channels 2 and 3 each support up to 2 A continuous output current. Peak current limiting is set at 3.7 A for channels 2 and 3, offering a safety margin above the continuous rating to handle load transients without triggering a fault shutdown.
Which input voltage sources are compatible with TPS65266RHBT for a portable device design?
TPS65266RHBT accepts input voltages from 2.7 V to 6.5 V, making it compatible with a single-cell Li-ion battery (nominal 3.7 V, minimum 2.7 V) as well as 5 V USB or regulated adapter inputs. This wide input tolerance means the three output rails remain regulated even as the battery discharges from 4.2 V down to its cutoff voltage.
How does integrating three buck converters in TPS65266RHBT reduce design complexity compared to discrete regulators?
Using TPS65266RHBT replaces three separate single-channel buck converter ICs plus their individual gate-driver and compensation networks, cutting the component count by approximately 20 to 30 passive parts per design. The 32-pad QFN package concentrates all three power stages in a footprint smaller than 5 mm × 5 mm, significantly shrinking the power management section of portable PCB designs.
What control architecture does TPS65266RHBT use and how does it affect load transient performance?
TPS65266RHBT uses current-mode PWM control, which inherently provides a faster inner current loop response compared to voltage-mode control. This allows the output voltage to recover from a 1 A load step within a few microseconds with minimal overshoot, making the device suitable for processors and FPGAs that exhibit rapid dynamic current demands of up to 2 A per rail.
