ISL6236AIRZ - Renesas Electronics

Description: The ISL6236A dual step-down, switch-mode power-supply (SMPS) controller generates logic-supply voltages in battery-powered systems. The ISL6236A includes two pulse-width modulation (PWM) controllers, 5V/3. 3V and 1. 5V/1. 05V. The output of SMPS1 can also be adjusted from 0. 7V to 5. 5V. The SMPS2 output can be adjusted from 0V to 2. 5V by setting REFIN2 voltage. An optional external charge pump can be monitored through SECFB. This device features a linear regulator providing 3. 3V/5V, or adjustable from 0.

ISL6236AIRZ 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, wide traces for the power paths. Avoid routing sensitive signals near the inductor.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-10 μH). Consider the inductor's physical size, core material, and operating frequency when selecting an inductor.
  • The ISL6236AIRZ can handle input voltages up to 28V, but the recommended maximum input voltage is 24V to ensure reliable operation and minimize stress on the internal components.
  • The output voltage can be adjusted by changing the resistor divider network connected to the FB pin. Use the formula in the datasheet to calculate the required resistor values for the desired output voltage.
  • The EN (enable) pin is used to turn the converter on or off. Connect the EN pin to VIN to enable the converter, or connect it to GND to disable it. You can also use an external signal to control the EN pin for dynamic voltage scaling or power sequencing.
