Most DC-to-DC converters use output-filter ceramic capacitors with very low equivalent series resistance (ESR). This causes a double pole at the resonance frequency .
To achieve an adequate bandwidth and phase margin for the DC-to-DC converter, the device requires compensation around the resonance frequency. To achieve this, configure the error amplifier as type-3 compensation. The TLV2426x-Q1 series features a wide bandwidth UGBD of 6 MHz with rail-to-rail output for increased dynamic range. These features are designed for DC-to-DC loop compensation with any LC filter.
