PISM-101M-04 - Fastron

PISM-101M-04 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  For optimal performance, it's recommended to follow a 4-layer PCB stackup with a solid ground plane, and to use thermal vias to dissipate heat from the module. A minimum of 2oz copper thickness is recommended for the top and bottom layers.
• How do I ensure reliable power sequencing and voltage regulation for the module?
  It's essential to follow a controlled power-up sequence, ensuring that the input voltage (VIN) is stable before applying the enable signal (EN). A high-quality voltage regulator with low noise and high PSRR is recommended to power the module.
• What are the recommended input and output capacitors for the module?
  For optimal performance, it's recommended to use low-ESR capacitors with a minimum capacitance of 10uF for the input (VIN) and 4.7uF for the output (VOUT). X5R or X7R dielectric capacitors are suitable for this application.
• How do I protect the module from overcurrent and overvoltage conditions?
  It's recommended to add external overcurrent protection (OCP) and overvoltage protection (OVP) circuits to prevent damage to the module. A fuse or a current-limiting resistor can be used for OCP, while a voltage supervisor or a zener diode can be used for OVP.
• What is the recommended operating temperature range for the module?
  The recommended operating temperature range for the PISM-101M-04 is -40°C to +85°C. However, it's essential to ensure that the module is operated within the specified temperature range to maintain its performance and reliability.
