The NCP1589L is a low-cost PWM controller that operates from 5 V to 12 V. The device is capable of generating output voltages as low as 0.8 V and can convert from voltages as low as 2.5 V. It is simple to operate, provides the best level of integration, reduces power supply size, and lowers cost. It operates in ramp pulse modulation mode for excellent load step and release response. In addition to fast transient response, it includes a 1.5 A gate driver design and light load efficiency features such as adaptive non-override circuitry and diode emulation. Its normal operating range of 200~500 kHz in continuous current conduction mode reduces current at light loads for further power savings. Protection features include programmable overcurrent protection, output overvoltage and undervoltage protection, and input undervoltage lockout.
