ZHCSQS6C November 2007 – January 2024 TPS5420-Q1
PRODUCTION DATA
The internal voltage feed forward provides a constant DC power stage gain despite any variations with the input voltage. This greatly simplifies the stability analysis and improves the transient response. Voltage feed forward varies the peak ramp voltage inversely with the input voltage so that the modulator and power stage gain are constant at the feed forward gain, i.e.:
The typical feed forward gain of TPS5420 is 25.
