  Part Number: TPS628511 Hello TI-Team, Can I use the SS/TR-Pin to control the load current? Measure the load current by adding an ext. Opamp as current-controller and feed back the signal to SS/TR-Pin to reduce the duty-cycle. Best regards, Frank

• RE: TLV62568A: How much load capacitance is support

  

  Varun John

  Hi Yongfei, The TLV62568A won't be able to support more than 47uF output cap. Higher output cap causes the control loop to be unstable. Please use TPS628511, TPS628501 or TPS628301 to support larger output caps. Best regards, Varun

  Thanks for explaining. Would TPS628511 (or TPS628501) work for you? We also have a power module version, with inductor integrated, releasing soon: https://www.ti.com/lit/ug/slvucp5/slvucp5.pdf Chris
