... Data Sheet Advanced PWM and Dual Linear Power Control The HIP6017 provides the power control and protection for three output voltages in high-performance microprocessor and computer applications. The IC integrates a PWM controller, a linear regulator and a linear controller as well as the monitoring and protection functions into a single 28 lead SOIC package. The PWM controller regulates the microprocessor core voltage with a synchronous-rectifi ...

... V33 (Pin 10) Connect this pin to the 3.3VDC supply. Description Operation The HIP6017 monitors and precisely controls 3 output voltage levels (Refer to Figures 1, 2, and 3 designed for microprocessor computer applications with 3.3V and 5V power and 12V bias input from an ATX power supply. The IC has one PWM controller, a linear controller, and a linear regulator ...

... Initialization The HIP6017 automatically initializes upon receipt of input power. By the time the soft-start (SS) voltage reaches 4V, the 3.3V input has to be high enough such that the two linear outputs ( have exceeded their under-voltage OUT2 OUT3 threshold. A typical ATX supply meets this requirement. The Power-On Reset (POR) function continually monitors the input supply voltages ...

... The soft-start cycle repeats at T3 and trips the over-current comparator. The SS pin voltage increases and the counter increments to 3. This sets the fault latch to disable the converter. The fault is reported on the FAULT/RT pin. 2-217 HIP6017 on the VCC IN 10V ...

... The peak surge current occurs during the initial output voltage rise to 80% of the set value. 2-218 HIP6017 Shutdown The PWM output does not switch until the soft-start voltage (V ) exceeds the oscillator’s valley voltage. Additionally, the SS reference on each linear’ ...

... There are two sets of critical components in a DC-DC converter using a HIP6017 controller. The power components are the most critical because they switch large amounts of energy. The critical small signal components connect to sensitive nodes or supply critical bypassing current. The power components should be placed fi ...

... MOSFET’s body diode. The gate- charge losses are proportional to the switching frequency (F ) and are dissipated by the HIP6017, thus not S contributing to the MOSFETs’ temperature rise. However, large gate charge increases the switching interval, t which increases the upper MOSFET switching losses ...
