ISL59446IRZ - Renesas Electronics

Description: The ISL59446 is a triple channel 4:1 multiplexer featuring integrated amplifiers with a fixed gain of 2, high slew rate and excellent bandwidth for video switching. The device features a three-state output (HIZ), which allows the outputs of multiple devices to be tied together. A power-down mode (ENABLE) is included to turn off unneeded circuitry in power sensitive applications. When the ENABLE pin is pulled high, the part enters a power-down mode and consumes just 14mW.

ISL59446IRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10uF capacitor between the VIN pin and GND, and a 1uF capacitor between the VOUT pin and GND.
  • Ensure that the output capacitor is within the recommended range (10uF to 100uF) and has a low ESR (< 1 ohm). Also, keep the feedback loop components (R1, R2, and C1) close to the IC and use a low-impedance connection to the output capacitor.
  • The maximum input voltage that can be applied to the VIN pin is 18V. Exceeding this voltage may damage the IC.
  • The output voltage can be calculated using the formula: VOUT = 1.25 x (1 + R2/R1). The output current limit is internally set to 3.5A, but can be adjusted using an external resistor (RILIM) connected between the ILIM pin and GND.
  • The EN (enable) pin is used to turn the regulator on or off. Connect the EN pin to VIN to enable the regulator, or to GND to disable it. The EN pin can also be used to implement a power-good function by connecting it to a voltage monitor or a microcontroller.
