DIFFERENT +5V BIAS SUPPLY SCHEMES APPLICATION SCHEMATIC
The SP6134CU VCC Bias Supply can be derived from Vin or external bias with several
biasing options depending on the output power, load current, and additional biasing for
the protection feature circuitry under many different application considerations. For
example the transistor plus zener diode +5V bias supply could be used as shown in
Figure 11. The reason is that if there is significant SP6134CU output stage current is
needed to drive both the external MOSFET gate charges especially when application
that require a few external parallel MOSFETs to achieve high output current. However,
Figure 12 shows a very simple zener diode +5V VCC bias supply when very low
external gate charge is used. In any case the SP6134CU is consuming no more than
16mA since both of the external MOSFETs gate charge is small base on its smaller
footprint selections. Figure 13 shows an application circuit with SP6134CU using Sipex
SPX5205 Low Drop Out (LDO) Voltage Regulator for +5V VCC Bias Supply. Note that
there is an advantage of using the LDO for the +5V VCC bias since the LDO output
voltage is very stable and precise allowing other to derived the voltage from it as
example when additional over current clamp limit is added.
