NCP1589A, NCP1589B Low Voltage Synchronous Buck Controller The NCP1589A/B is a low cost PWM controller designed to operate from a 5 V or 12 V supply.
This device is capable of producing an output voltage as low as 0.
8 V.
This device is capable of converting voltage from as low as 2.
5 V.
This 10−pin device provides an optimal level of integration to reduce size and cost of the power supply.
Features include a 1.
5 A gate driver design and an internally set 300 kHz or 600 kHz oscillator.
In addition to the 1.
5 A gate drive capability, other efficiency enhancing features of the gate driver include adaptive non−overlap circuitry.
The NCP1589A/B also incorporates an externally compensated error a...
