APW7058 General Description
The APW7058 integrates one synchronous-rectified Buck PWM controller and one linear controller to provide two regulated voltages for graphics cards and other embedded processor applications. The PWM controller which drives dual N-channel MOSFETs uses fixed 600kHz frequency, voltage-mode PWM control and integrates power-on-reset(POR), built-in soft-start, output under-voltage monitoring and shutdown functions into a single chip. The linear controller which drives a N-channel MOSFET bypass transistor allows users to optimize the transient response by external components. The POR circuit with hysteresis monitors both 5VCC and 12VCC supply voltages to start up/shutdown the IC at power-on/off. An internal 0.8V temperature-compensated reference is designed to meet the low output voltage requirement for further applications. The built-in soft-start function sets the soft-start interval to prevent the output voltages from overshoot as well as limiting the input currents. The under-voltage protections monitor the voltages at FB and FB2 for short-circuit protection. The under-voltage protections cycle the soft-start function until 3 times of UVP events are happened. Pulling and holding the FB2 pin above 1.28V to disable the both controllers.
