Product Summary
The TPSM8291x series is a power module with an inductor mounted on top of the IC. Among them, this product is a step-down switching regulator that achieves high efficiency, low noise, and low ripple. It also operates with a fixed switching frequency of 2.2MHz or 1MHz and can be synchronized to an external clock. It achieves a low frequency noise level similar to a low noise linear regulator (LDO). This product is recommended for measurement equipment, radio equipment, etc. (Recommended as a power supply for ADCs, clocks, etc.)
Recommended for
- Those who use switching regulators and linear regulators to eliminate noise
- Small equipment with limited space and wanting to insert a ferrite bead just in case

What is the ferrite bead filter compensation function?
In the case of conventional power supply ICs, if a ferrite bead is mounted externally, the power supply IC may oscillate due to the voltage drop due to the DC resistance of the ferrite bead or the parasitic components (L and C) of the ferrite bead. Since the TPSM82913 has a ferrite bead filter compensation function, it is possible to form a feedback circuit including an external ferrite bead. This results in an output voltage ripple of less than 10µV RMS. There is almost no need to consider voltage drop due to ferrite beads or power supply IC oscillation.
This device is recommended for those who need to suppress noise from switching regulators.

with Integrated Ferrite Bead Filter Compensation
What is a Hot Rod™ package?
By directly attaching the die and lead frame, the structure does not use the wire bonding used in conventional packages. By doing so, it is possible to minimize the parasitic components inside the package, reduce the noise level, improve efficiency, and reduce the package size.
