ISL95870BHRZ-T - Renesas Electronics

Description: The ISL95870, ISL95870A, ISL95870B ICs are Single-Phase Synchronous-Buck PWM regulators featuring Intersil’s proprietary R4 Technology™. The wide 3. 3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL95870A and ISL95870B are low-cost solutions for applications requiring dynamically selected slew-rate controlled output voltages. The soft-start and dynamic setpoint slew-rates are capacitor programmed. Voltage identification logic-inputs select four (ISL9

ISL95870BHRZ-T Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL95870BHRZ-T involves keeping the power and ground planes separate, using a solid ground plane, and placing the input and output capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitors are of high quality and have low ESR. It's also important to decouple the input and output with capacitors and to use a low-ESR input capacitor.
  • The ISL95870BHRZ-T can handle input voltages up to 25V, but it's recommended to operate within the specified input voltage range of 7V to 20V for optimal performance and reliability.
  • The ISL95870BHRZ-T has a resistor-programmable output voltage. To program the output voltage, connect a resistor (RFB) between the FB pin and the output voltage. The output voltage can be calculated using the formula: VOUT = 0.8V x (RFB / 10kΩ) + 0.8V.
  • The ISL95870BHRZ-T has a thermal derating of 1.5% per °C above 25°C. This means that the maximum output current will decrease as the temperature increases.
