New Semiconductor & Integrated Circuit Devices

AC-DC Controllers & Regulators
 

NCP1631  Interleaved, 2-Phase Power Factor Controller

  • Two small stages, versus one large stage, shrinks component size, improves heat distribution; ideal for flat panel TVs and ultra-slim notebook adapters
  • Frequency Clamped Critical Conduction mode and frequency foldback linearly lowers the clamping frequency as a function of power, optimizing efficiency across the load range
  • 180° phase shifted outputs significantly reduce current ripple, which lowers EMI and reduces bulk capacitor rms current
 
 

DC-DC Controllers, Converters, & Regulators
 

NCP693  1 A CMOS LDO Voltage Regulator

  • Output voltage options of 0.8, 1.0, 1.2, 2.5, 3.3 V
  • Output voltage accuracy of +/- 1% (typ)
  • uDFN-6 package (2 mm x 1.8 mm)
 
 

Voltage Controllers, References, & Supervisors
 

NCP372  Positive & Negative Overvoltage Protection IC

  • Positive (+28 V) and negative (-28 V) overvoltage protected, with system disconnected from the input voltage if limits are exceeded; reverse current blocking
  • Both low RDS(on) MOSFETs are integrated to cut cost and minimize pcb area
  • Extremely low quiescent current to maximize operating time in portable equipment
