The noise source from T-CON interferes with the DC supply loop between the DC-to-DC converter
and the source driver IC.
Conversions from ac take place using linear and switch-mode power supplies (SWPS) and dc-to-dc converters
either externally, in the form of dongles or wall-warts, or internally as part of the circuitry.
ADI's isoPower integrated, isolated dc-to-dc converter
uses the same chip-scale transformer technology, but instead of transmitting data, isoPower employs switches, rectifiers, and regulators to generate power that is isolated to the same degree as the data channels.
The overall amplifier structure employing the DC-to-DC converter
is shown in Figure 7.

Adrian Roche, a design engineer at IntePro Systems, said that the company recently developed the EL 2000 HS electronic load featuring rise times faster than 1 ps to test point-of-load (POL) and point-of-use (POU) DC-to-DC converters
Established in Silicon Valley in 2004, PAM offers a portfolio of products that includes Class D audio amplifiers, DC-to-DC converters
and light-emitting diode (LED) backlighting drivers.
He covers fundamentals of direct current (DC) power supply design and linear regulators, switching power supply topologies and design fundamentals, power semiconductors, resonant converters and wireless power supplies, the control loop design of DC-to-DC converters
, power management, off-the-line switching power supplies, rechargeable batteries and their management, and protecting systems from surges and transients.
It is ideal for testing linear regulators (LDO), switching DC-to-DC converters
, power supply modules, wall adapters, and more.
The unique architecture of the IDT P95020 features a best-in-class high-fidelity audio subsystem, clock generation, resistive touch controller, backlight LED driver, Li+/Polymer battery charger, multi-channel DC-to-DC converters
and a high resolution analog-to-digital converter (ADC).
Its subsystems consist of multiple switch-mode DC-to-DC converters
and low-dropout (LDO) regulators, battery charge management, white LED drivers, low-power stereo audio and voice codecs with a mixer function, Class-D amplifier and headphone driver, a PLL for on-chip and off-chip clock generation and a touch-screen controller.
