NCP1546
1.5 A, 170 kHz, Buck
Regulator with
Synchronization Capability
The NCP1546 is a 1.5 A buck regulator IC operating at a
fixedfrequency of 170 kHz. The device uses the V2
t control
architecture to provide unmatched transient response, the best overall
regulation and the simplest loop compensation for today’s highspeed
logic. The NCP1546 accommodates input voltages from 4.5 V to 40 V
and contains synchronization circuitry.
The onchip NPN transistor is capable of providing a minimum of
1.5 A of output current, and is biased by an external “boost” capacitor
to ensure saturation, thus minimizing onchip power dissipation.
Protection circuitry includes thermal shutdown, cyclebycycle
current limiting and frequency foldback.
Features
V2 Architecture Provides UltraFast Transient Response, Improved
Regulation and Simplified Design
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 PowerDown Option
1.0 mA Quiescent Current During PowerDown
Thermal Shutdown
SoftStart
PbFree Packages are Available
