NCP1589B Datasheet | onsemi

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 k Hz or 600 k Hz 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 pensated error amplifier. Protection Features include programmable short circuit protection and undervoltage lockout (UVLO). Features - VCC Range from 4.5 V to 13.2 V - 300 k Hz and 600 k Hz Internal Oscillator - Boost Pin Operates to 30 V - Voltage Mode PWM Control - Precision 0.8 V Internal...
