Overview
NCP1587, NCP1587A
Low Voltage Synchronous
Buck Controller
The NCP1587 and NCP1587A are low cost PWM controllers designed to operate from a 5 V or 12 V supply.
These devices are capable of producing an output voltage as low as 0.
8 V.
These 8−pin devices provide an optimal level of integration to reduce size and cost of the power supply.
The NCP1587/A provide a 1 A gate driver design and an internally set 275 kHz (NCP1587) and 200 kHz (NCP1587A) oscillator.
In addition to the 1 A gate drive capability, other efficiency enhancing features of the gate driver include adaptive non−overlap circuitry.
The devices also incorporate an externally compensated error amplifier and a capacitor programmabl...
