NCP1547DG Datasheet - ON Semiconductor
ON Semiconductor
The NCP1547 is a 1.5 A buck regulator IC operating at a fixed−frequency of 340 kHz. The device uses the V2™ control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high−speed logic. The NCP1547 accommodates input voltages from 4.0 V to 40 V and contains synchronization circuitry.
FEATUREs
• V2 Architecture Provides Ultra−Fast Transient Response, Improved Regulation and Simplified Design
• Wide Operating Range: 4 V to 40 V
• 2.0% Error Amp Reference Voltage Tolerance
• Switch Frequency Decrease of 4:1 in Short Circuit Conditions Reduces Short Circuit Power Dissipation
• BOOST Lead Allows “Bootstrapped” Operation to Maximize Efficiency
• Sync Function for Parallel Supply Operation or Noise Minimization
• Shutdown Lead Provides Power−Down Option
• 1.0 A Quiescent Current During Power−Down
• Thermal Shutdown
• Soft−Start
• These are Pb−Free Devices
