Description

The LM3000 is a dual output synchronous buck controller which is designed to convert input voltages ranging from 3.3V to 18.5V down to output voltages as low as 0.6V. The two outputs switch at a constant programmable frequency of 200 kHz to 1.5 MHz, with the second output 180 degrees out of phase from the first to minimize the input filter requirements.

Key Features

  • 2 VIN Range FROM 3.3V to 18.5V
  • Output Voltage From 0.6V to 80% of VIN
  • Remote Differential Output Voltage Sensing
  • 1% Accuracy at FB Pin
  • Interleaved Operation Reduces Input Capacitors
  • Frequency Sync/Adjust From 200 kHz to 1.5 MHz
  • Startup With Pre-Bias Load
  • Independent Power Good, Enable, Soft-Start and Track
  • Programmable Current Limit Without External Sense Resistor
  • Hiccup Mode Short Circuit Protection
