TPSM82912 Datasheet (Texas Instruments) - Low-Noise and Low-Ripple Buck Power Module

TPSM82912, Low-Noise and Low-Ripple Buck Power Module

The TPSM8291x devices are a family of highefficiency, low-noise and low-ripple current mode synchronous buck power modules.

The devices are ideal for noise sensitive applications that would normally use an LDO for post regulation such as high-speed ADCs, clock and jitter cleaner, serializer, de-ser

TPSM82912 Features

* Low output noise < 20 µVRMS (100 Hz to 100 kHz)

* Low output voltage ripple < 10 µVRMS after ferrite bead

* High PSRR of > 65 dB (up to 100 kHz)

* 2.2-MHz or 1-MHz fixed frequency peak current mode control

* Synchronizable with external clock (optional)
