Low Voltage Synchronous

Buck Controller with Light

Load Efficiency and

MARKING

The NCP1589D 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 and converting voltage from as low as

2.5 V. It is easy to operate and provides an optimal level of integration

to reduce size and cost of the power supply. It operates in Ramp Pulse

Modulation mode for superior load step and release response. In

addition to fast transient response, it also includes a 1.5 A gate driver

design and light load efficiency features such as adaptive non−overlap

circuitry and diode emulation. It normally operates at a range of

200−500 kHz in continuous current conduction mode, which reduces

with current at light load for further power saving. Protection features

include programmable overcurrent protection, output overvoltage and

undervoltage protection and input undervoltage lockout (UVLO).
