QFN-FCMOD (VCE)-16-18.8 mm² 4.7 x 4
The TPSM82916 is a high-efficiency, low noise, and low ripple current mode synchronous buck module. The device is designed for noise sensitive applications that normally use an LDO for post regulation such as high-speed ADCs, clock and jitter cleaner, serializer, deserializer, and radar applications.
To reduce the output voltage ripple, the device loop compensation is designed to operate with an optional second-stage ferrite bead L-C filter. Low-frequency noise levels, similar to a low-noise LDO, are further achieved by filtering the internal voltage reference with a capacitor connected to the NR/SS pin. Combined, these features allow for an output voltage ripple below 10µVRMS.
The device operates at a fixed switching frequency of 2.2MHz, 1.4MHz, or 1MHz, and can be synchronized to an external clock. An optional spread spectrum modulation scheme spreads the DC/DC switching frequency over a wider span, which lowers the mixing spurs.
