  • TPS62A04B: Phase margin/gain margin

    Resolved
    Part Number: TPS62A04B Tool/software: Hi, Does TPS62A04B have phase margin and gain margin specification? Or can reference normal case gain < -6dB, phase >45degee? Thanks! Jeff

  • TPS62A04B: The switch frequency goes to much higher during 0.5A-1.2A output current

    Part Number: TPS62A04B Tool/software: This chip is supposed to have a fixed 2.2MHz switch frequency for medium to heavy load and lower frequency for light load as it works as PFM mode. While in our design, I found the switch frequency can go high to 4…

  • TLV62595: UVLO < Input voltage < Output Voltage: Pass-through?

    Resolved
    Part Number: TLV62595 Other Parts Discussed in Thread: TPS62A06 , TPS62A04B Tool/software: When the DC-DC Buck input voltage is greater than the UVLO threshold but less than the target output voltage, what happens? Does the input voltage just pass through…
