14 / 52 page ![]() Device description L6730 - L6730B 14/52 5.2 Internal LDO An internal LDO supplies the internal circuitry of the device. The input of this stage is the VCC pin and the output (5V) is the VCCDR pin (see Figure 4.). 5.3 Bypassing the LDO to avoid the voltage drop with low Vcc The LDO can be by passed by providing 5V voltage directly to VCCDR. In this case Vcc and VCCDR pins must be shorted together as shown in Figure 5. VCCDR pin must be filtered with at least 1 µF capacitor to sustain the internal LDO during the recharge of the bootstrap capacitor. VCCDR also represents a voltage reference for Tmask pin, S/O/U pin (L6730) or CC/O/U pin (L6730B) and PGOOD pin (see Table 3: Pins connection). If Vcc ≈ 5V the internal LDO works in dropout with an output resistance of about 1Ω. The maximum LDO output current is about 100mA, and so the output voltage drop can be 100mV. The LDO can be bypassed to avoid this. Figure 4. LDO block diagram. Figure 5. Bypassing the LDO LDO 4.5V ÷14V |
