ISL62392CHRTZ-T - Renesas Electronics

Description: The ISL62392C controller generates supply voltage for battery-powered systems. It includes two pulse-width modulation (PWM) controllers, adjustable from 0. 6V to 5. 5V, and a linear regulator (LDO3) that generates a fixed 3. 3V and can deliver up to 100mA. The ISL62392C includes on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown. The patented R3 PWM control scheme provides a low jitter system with

ISL62392CHRTZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The selection of input and output capacitors depends on the specific requirements of your application, including the input voltage range, output current, and ripple requirements. Renesas provides guidance on capacitor selection in the datasheet and application notes, and also offers a capacitor selection tool on their website.
  • The ISL62392CHRTZ-T has an operating temperature range of -40°C to +125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's essential to ensure proper thermal management and heat sinking to prevent overheating.
  • The ISL62392CHRTZ-T has a built-in overcurrent protection (OCP) feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. Short-circuit detection can be implemented using the device's current sense pins and an external comparator or microcontroller.
  • The recommended startup sequence for the ISL62392CHRTZ-T is to first apply the input voltage, then enable the device by setting the EN pin high, and finally apply the output load. This sequence helps prevent unwanted startup behavior and ensures proper operation.
