  • [FAQ] LM26480: Is there a reference design of power up sequence implemented by RC delay on EN pin?

    Part Number: LM26480 Yes; a set of RC (Resistor and Capacitor) values were used on TI LM26480 EVM with VCC=3.3V on 3 "EN" pins (ENSW2, ENLDO1, ENLDO2) to control the power up delay for the sequence. ENSW1 connects to VCC directly without RC delay. …

  • [FAQ] TPS43330-Q1: TPS43330/30A/2/3/5/6/7-Q1 Devices Difference

    Part Number: TPS43330-Q1

  • [FAQ] TPS43330-Q1: TPS43330/30A/2/3/5/6/7-Q1 Operation Mode Details

    Part Number: TPS43330-Q1

  • [FAQ] TPS43330A-Q1: What is the minimum possible duty cycle for the booster?

    Part Number: TPS43330A-Q1 The boost controller allows the device to operate down to 2 V at the input; the duty cycle of Boost converter D = 1 – (input voltage/output voltage); so, it depends on your output voltage selection (7 V, 8.85 V, or 10 V), the…

  • [FAQ] TPS6594-Q1: TPS6594-Q1 and LP8764-Q1: Can unused buck feedback pins be used to monitor external voltages?

    Part Number: TPS6594-Q1 Yes, any BUCK feedback pin that is not being used for the BUCK feedback can be used as a voltage monitor. Unused feedback pins include FB_B3 on a 3-phase or 4-phase BUCK and FB_B4 on a 4-phase BUCK. Also, any feedback pins on…

  • [FAQ] TPS6594-Q1: How to reprogram non-volatile memory on TPS6594-Q1 and LP876x-Q1

    Part Number: TPS6594-Q1 The TPS6594-Q1 and LP876x-Q1 devices have reprogrammable non-volatile memory. The memory can be updated over the device's I2C or SPI communication. This process is described in the "Scalable PMIC NVM Update Guide" https://www…
