Hybrid hysteretic control, a new patented control method, enables up to 10 times faster transient response and reduces output capacitance
The most common solution is to increase the output capacitance
The NCP51200 maintains a fast transient response and only requires a minimum output capacitance
The stray components such as the output capacitance
of the power MOSFETs and the leakage inductance of the transformer are used advantageously to provide zero voltage turn-on of the switches (Gwan-Bon, Tae-Sung, Gun-Woo, & Myung-Joong, 2004).
Coss is the output capacitance
, as seen looking at the Drain with respect to the Source.
Lopt] is the optimum impedance, and it is inversely proportional to the frequency and the output capacitance
However, the PAE is degraded by the switching transistor on-resistance, losses in the output filter and matching network, and discrete components for the dc feed and additional output capacitance
They offer low output capacitance
and high closed loop bandwidth to keep up with the advanced maximum power point tracking (MPPT) algorithms used in today's grid-tied inverters.
The LDO regulators also deliver best-in-class transient response, minimizing the amount of output capacitance
But with larger FETs, because they have higher than normal output capacitance
, the current loss at the moment when the FET is switched on (switching loss) is greater.
During the design of a power supply, careful consideration must be given to the equivalent series resistance and ripple current, as well as the total output capacitance
The SuperSwitcher II(tm) family has been tailored to be Any Capacitor(tm) stable independent of output ESR, thus solving the perennial problem that stability power designers have faced with respect to distributed output capacitance
