... The HIP6004A monitors the output voltage with a window comparator that tracks the DAC output and issues a Power Good signal when the output is within 10%. The HIP6004A protects against over-current and over-voltage conditions by inhibiting PWM operation. Additional built-in over-voltage protection triggers an external SCR to crowbar the input supply ...

... GND (Pin 11) Signal ground for the IC. All voltage levels are measured with respect to this pin. 2-66 HIP6004A PGOOD (Pin 12) PGOOD is an open collector output used to indicate the status of the converter output voltage. This pin is pulled low RT when the converter output is not within 10% of the OVP DACOUT reference voltage ...

... Functional Description Initialization The HIP6004A automatically initializes upon receipt of power. Special sequencing of the input supplies is not necessary. The Power-On Reset (POR) function continually monitors the input supply voltages. The POR monitors the bias voltage at the V pin and the input voltage (V CC the OCSET pin. The level on OCSET is equal to V fi ...

Output Voltage Program The output voltage of a HIP6004A converter is programmed to discrete levels between 1.8V 3.5V . The voltage identification (VID) pins program an DC internal voltage reference (DACOUT) with a TTL- compatible 5-bit digital-to-analog converter (DAC) ...

... Given a sufficiently fast control loop design, the HIP6004A will provide either 0% or 100% duty cycle in response to a load transient. The response time is the time required to slew the inductor current from an initial current value to the transient current level ...

... Standard-gate MOSFETs are normally recommended for use with the HIP6004A. However, logic-level gate MOSFETs can be used under special circumstances. The input voltage, upper gate drive level, and the MOSFET’s absolute gate-to- source voltage rating determine whether logic-level MOSFETs are appropriate ...
