ZHCSJU9E January 2007 – June 2019 TPS40077
PRODUCTION DATA.
The TPS40077 allows the user to construct synchronous voltage-mode buck converters with inputs ranging from 4.5 V to 28 V and outputs as low as 700 mV. Predictive Gate Drive circuitry optimizes switching delays for increased efficiency and improved converter output-power capability. Voltage feed forward is employed to ease loop compensation for wide-input-range designs and provide better line transient response.
The TPS40077 incorporates circuitry to allow start-up into a preexisting output voltage without sinking current from the source of the preexisting output voltage. This avoids damaging sensitive loads at start-up. An integrated power-good indicator is available for logic (open-drain) output of the condition of the output of the converter.
