RT5715GQW - RICHTEK

Description: The RT5715A is a 2A, high-efficiency, Advanced ConstantOn-Time (ACOT® ) synchronous step-down converter. The device operates with input voltages from 2.5V to 5.5V. The device can program the output voltage between 0.45V to VIN. The low quiescent current design with the integrated low RDS(ON) power MOSFETs achieves high efficiency over the wide load range. The advanced COT operation allows transient responses to be optimized over a wide range of loads, and output capacitors to efficiently reduce exte

RT5715GQW Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short and wide traces for the power lines.
  • Monitor the input voltage, output current, and junction temperature to ensure they are within the specified limits. Use thermal design and layout techniques to keep the junction temperature below 125°C.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22uF is recommended. The capacitor should be placed close to the VIN pin and have a low impedance path to the power plane.
  • Choose an output capacitor with low ESR and high ripple current rating. A 22-47uF ceramic capacitor (e.g., X5R or X7R) is a good starting point. Consider the output voltage, output current, and ripple requirements when selecting the capacitor.
  • The EN (enable) pin is used to turn the regulator on or off. Connect the EN pin to VIN or a logic signal to enable the regulator. When EN is low, the regulator is disabled, and the output is turned off.
