Texas Instruments TPS62913

Description

The TPS6291x devices are a family of high efficiency low noise and low ripple synchronous buck converters. 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-serializer, and Radar applications.

Features

• Low output 1/f 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)
• Integrated loop compensation supports ferrite bead for second stage L-C filter (optional)
• Spread spectrum modulation (optional)
• 3.0-V to 17-V input voltage range
• 0.8-V to 5.5-V output voltage range
• 57-mΩ/20-mΩ RDSon
• Output voltage accuracy of ±1%
• Precise enable input allows
• User-defined undervoltage lockout
• Exact sequencing
• Adjustable soft start
• Power-good output
• Output discharge (optional)
• -40°C to 150°C junction temperature range
• 2.0-mm x 2.0-mm QFN with 0.5-mm pitch
• Create a custom design using the TPS6291x with the WEBENCH Power Designer

Typical applications

• Telecom infrastructure
• Test and measurement
• Medical
