RG and RF form a potential divider whose function is to keep the EAP pin within the upper limit of its common mode input range (VCM_MAX = 3.6 V) when there is no current in the photo-transistor. RG is connected to VREF and this constraint on the voltage at the EAP pin gives: VREF...

First, the 95D-sh-UCC cells were subcutaneously injected into the flanks of nude mice, and the mice were observed for 32 days. The average weight and volume of the tumours were found to be significantly lower in the sh-UCC group than in the sh-NC group (Fig. 6A–C), indicating that...
For the auto-recovery fault protections, if the controller is in 1.5-s auto-recovery fault state, LZC can reset the timer and speed up the restart attempt. The two redundant XCD pins help to provide the X-cap discharge function even when one pin is in fail-open condition. To form the ...
In general, the system designer should attempt to use larger traces on the PC board where possible to spread the heat away form the device more effectively. For information on the PowerPAD package, see the technical brief, PowerPad? Thermally Enhanced Package, Texas Instruments literature number ...
The shunt-regulator compensation network, ZFB, is determined using well-established design techniques for control-loop stability. Typically, a Type-II compensation network is used. An effective approach is to set ZFB to be a capacitor, ZFB = CFB to form an integrator, and adding a bypass ...
