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 amplifier. Protection

features include programmable short circuit protection and

undervoltage lockout (UVLO).
