LM3478MAX/NOPB +BOM

2.97~40V Wide Input Range Boost/SEPIC/Flyback DC-DC Controller

LM3478MAX/NOPB General Description

Furthermore, the LM3478 offers power-saving shutdown mode, reducing the total supply current to just 5 µA and enabling power supply sequencing for added efficiency. The internal soft-start feature limits the inrush current during start-up, helping to prevent sudden power surges and ensuring a smooth and controlled startup process

Key Features

  • 8-lead VSSOP-8 and SOIC-8 packages
  • Internal Push-Pull Driver With 1-A Peak Current Capability
  • Current Limit and Thermal Shutdown
  • Frequency Compensation Optimized With a Capacitor and a Resistor
  • Internal Soft Start
  • Current Mode Operation
  • Undervoltage Lockout With Hysteresis
  • Create a Custom Design Using the LM3478 with the WEBENCH Power Designer
