NCP1589, NCP1588, Low Voltage Synchronous Buck Controller
Pin No.
Symbol Description 1 BOOT Supply rail for the floating top gate driver.
To form a boost circuit, use an external diode to bring the desired input voltage to this pin (cathode connected to BOOT pin).
Connect a capacitor (CBOOT) between this pin and the LX pin.
Typical values for CBOOT r
NCP1589 Features
* include a 1.5 A gate driver design and an internally set 300ĂkHz 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 NCP158x also incorporates an externally compensated error amplifier. Protect
