VIN must be higher than the UVLO voltage setting, including after accounting for AC noise on VIN, for the DLPA3000 to fully operate. While 6.0 V is the min VIN voltage supported, TI recommends that the UVLO is never set below 6.21 V. 6.21 V gives margin above 6.0 V to protect against the case where someone suddenly removes VIN’s power supply which causes the VIN voltage to drop rapidly. Failure to keep VIN above 6.0 V before the mirrors are parked and VOFS, VRST, and VBIAS supplies are properly shut down can result in permanent damage to the DMD. Since 6.21 V is 0.21 V above 6.0 V, when UVLO trips there is time for the DLPA3000 and DLPC343x to park the DMD mirrors and do a fast shut down of supplies VOFS, VRST, and VBIAS. For whatever UVLO setting is used, if VIN’s power supply is suddenly removed enough bulk capacitance should be included on VIN inside the projector to keep VIN above 6.0 V for at least 100us after UVLO trips.
Not production tested.
Including rectifying diode.
Care should be taken not to exceed the max power dissipation. Please refer to Thermal Considerations.
Maximum depends linearly on oscillator frequency ƒOSC.
