MBM29DL161XTD Price Dual Output Buck-boost with Increased Output Current Capability Replacing NCP1052 by NCP1055, which is with a current limit of 680 mA, the output current capability is increased. Larger value ofinductor L is selected for high current. On the other hand, the current consumption of NCP1055 is higher than NCP1052 and the startup transient time is longer in a higher power application. Hence, the Vcc capacitor is increased. When the Vcc capacitor increased, its charging frequency is decreased. Output capacitor is also needed to be increased to reduce this lower-frequency charging current/ ripple. In addition, by adding one more auxiliary winding to the inductor a secondary output is made. A typical example is shown in Figure 11. In higher output current application, the load regulation is the major problem. The 5.lkl resistor plays an important role for the load regulation. The primary output voltage is higher than the secondary because it can increase the output current ability by stepping up the current in the transformer. The line regulation is shown in Figure 12 when the output currents are constant. MBM29DL161XTD on stock
