relatively high values of load, current flowing in the converter output inductor in the direction of the load will be bypassed around the energy transfer capacitor by the unidirectional conducting device and converter operation will be the same as a prior art zero-current switching forward converter...
1. A controller for a resonant discontinuous forward converter (RDFC), said forward converter including a transformer with first and second matched polarity windings and a switch to switch dc power to said first winding of said transformer, said converter further having a dc output coupled to sai...
Figure 1 shows the circuit diagram of a 2.5V, 20 A isolated forward converter that uses theMAX8540current mode controller (U1). At startup, the total capacitance at the VCCpin is charged through MOSFET Q7 and the parallel combination of resistors R30 and R22 from the dc input voltage...
The Benchmark AHB2 power amplifier and HPA4 headphone amplifier both feature feed-forward error correction. This correction system is an important subset of the patented THX-AAA™ (Achromatic Audio Amplifier) technology. It is one of the systems that

Without the use of an external pass transistor, failure of the converter output to power VCC above the VREG level will result in over temperature protection activating hiccup SIP11205 BLOCK DIAGRAM operation whenever the pre-regulator power dissipation becomes excessive. The external high- and low-...
Connect the resistor from the VDD pin to the input supply of the converter. Connect the capacitor from the VDD pin to PGND. There should not be excessive (more than a 200-mV) voltage drop across the resistor in normal operation. This places some constraints on the R-C values that can ...
Circuits and methods are described for decoding exemplary memory arrays of programmable and, in some embodiments, re-writable passive element memory cells, which are particularly useful for extremely dense three-dimensional memory arrays having more than one memory plane. In addition, circuits and metho...
This paper starts with an in-depth analysis of the balanced forward-flyback converter, and introduces ten operating modes in which this converter can operate. A boundary-conduction mode (BCM) controller for the magnetization current is developed and presented, and through simulations the PFC ...
