Key features include the negative adjustable output down to -5.5 V, up to 1 A output current, and a fixed-frequency PWM control topology for predictable EMI behavior. Its most distinctive feature is the filtered reference system: an external filter capacitor on the CAP pin suppresses low-frequency (1/f) noise from the lower frequency limit up to around 100 kHz, which is essential for high-performance telecommunication and RF systems where reference noise directly degrades phase noise and signal integrity. The synchronous rectification architecture integrates both power MOSFETs, reducing external component count and improving efficiency compared to asynchronous inverting designs. Fixed-frequency PWM operation allows straightforward filter design and predictable switching-frequency spurs. Typical applications include negative bias rails for RF amplifiers, VCO and PLL tuning supplies, gallium arsenide (GaAs) and silicon photonics bias, telecommunication line cards, and op-amp negative rails in precision analog signal chains. The low 1/f noise makes it especially suitable where the negative rail feeds noise-sensitive circuitry. Design consideration: because the inverting buck grounds the IC pin that would normally be the output in a standard buck, the maximum input voltage and current capability depend on the input-to-output voltage ratio; consult the TI datasheet application section and use the CAP-pin filter capacitor to achieve the specified low-noise performance.
