Texas Instruments TPS62914
17V VIN, 4.5A low-noise low-ripple buck converter with integrated ferrite-bead filter compensation
Overview
| Topology | Buck Converter |
| Input voltage | 3-17 V |
| Switching frequency | 1000-2200 kHz |
| Output 1 | 1.2 V / 4.5 A |
Description
The TPS6291x devices are a family of high-efficiency, low noise, and low ripple current mode synchronous buck converters. The devices are designed for noise sensitive applications that normally use an LDO for post regulation such as high-speed ADCs, clock and jitter cleaner, serializer, de-serializer, 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.
