This month we look at:

• LM25061/9 - Positive Low Voltage Limiting Hot Swap Controller
  • 2.9 - 17V Vin range
  • Current and power limiting protection
  • Pin- and function-compatible with the LM(2)5069
  • Programmable PGD via feedback pin (LM25061)
• LM3000 - Dual Synchronous Emulated Current-Mode Controller
  • 3.3 - 18.5V Vin range, output down to 0.6V
  • Emulated current mode (ECM)
  • 1% accuracy at FB pin over -20 to +85 deg C
  • Start up and pre-bias load
  • Separate error amp ground inputs
  • CLOCKOUT pin 90 deg out of phase from system clock
