... Connect this pin to a resistor divider to set the linear regulator output. Description Operation The HIP6019 monitors and precisely controls 4 output voltage levels (Refer to Figures 1, 2, and 3 designed for microprocessor computer applications with 5V power and 12V bias input from a PS2 or ATX power supply. The IC has 2 PWM controllers, a linear controller, and a linear regulator. The fi ...

... VID pins can be left open for a logic 1 input, because they are internally pulled current source. Changing the VID inputs during operation is not recommended. The 2-260 HIP6019 sudden change in the resulting reference voltage could toggle the PGOOD signal and exercise the over-voltage protection. All V ...

... Contact Intersil for evaluation board drawings of the component placement and printed circuit board. There are two sets of critical components in a DC-DC converter using a HIP6019 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 ...

... MOSFET’s body diode. The gate- is the FALL charge losses are proportional to the switching frequency (F ) and are dissipated by the HIP6019, 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. ...
