TAS5086 is a six-channel PWM processor from TI. It supports 32-, 44.1-, 48-, 88.2-, 96-, 176.4-, 192 kHz sampling rates, has a dynamic range of ≥105-dB and THD of <0.06%. It supports multiple data formats and clock rates.

The TPA0242 is a 2.8W audio power amplifier with DC volume control and MUX control. It has internal gain control, which eliminates external gain-setting resistors. It supports PC 99 desktop line-out and PC 99 portable into 8-Ω load. It can deliver 2.8W/Ch output power into 3-Ω load.

UC1823 UC2823 UC3823 is a high-performance PWM controller that is compatible with voltage or current-mode topologies. It has a 1.0MHz switching frequency, 50ns output propagation delay, 1.5A peak current, wide-bandwidth error amplifier, double pulse suppression, pulse current limiting, soft start/max. Duty Cycle Control, Hysteresis Under-Voltage Lockout, Low Start Up Current (1.1mA), Trimmed Bandgap Reference (5.1V ±1%).

The TPA6017A2 is a stereo audio power amplifier with internal gain control and 2W/Ch output power. It is suitable for notebook computers, PDAs, and other portable audio devices.

The UCC3808A family is a BiCMOS push-pull, high-speed, low-power, pulse-width modulator. The UCC3808A contains all of the control and drive circuitry required for off-line or dc-to-dc fixed frequency current-mode switching power supplies with minimal external parts count. The UCC3808A dual output drive stages are arranged in a push-pull configuration. Both outputs switch at half the oscillator frequency using a toggle flip-flop. The dead time between the two outputs is typically 60 ns to 200 ns depending on the values of the timing capacitor and resistors, thus limiting each output stage duty cycle to less than 50%.

TPA1517 is a 6W stereo audio power amplifier with thermal protection, compatible with TDA1517P, fixed gain of 20dB, high power outputs (6W per channel), mute and standby operation, available in surface mount and thermally enhanced package.

UCC1580-1,-2,-3,-4 UCC2580-1,-2,-3,-4 UCC3580-1,-2,-3,-4 SLUS292D is a series of high-performance pulse width modulation controllers from TI, which have a variety of features, including auxiliary switch activation function, programmable dead time (turn-on delay), voltage mode control and feedforward operation, programmable limits for both transformer voltage-second product and PWM duty cycle, high current gate driver for both main and auxiliary outputs, multiple protection features, with latched shutdown and soft restart low supply current (100 mA startup, 1.5 mA operation).

The TPA0213 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω impedance. The amplifier can be reconfigured on the fly to drive two stereo single-ended (SE) signals into headphones. This makes the device ideal for use in small notebook computers, PDAs, personal digital audio players, anywhere a mono speaker and stereo headphones are required. From a 5-V supply, the TPA0213 can deliver 2 W of power into a 4-Ω speaker. The gain of the input stage is set by the user-selected input resistor and a 50-kΩ internal feedback resistor (AV = − RF/RI). The power stage is internally configured with a gain of –1.25 V/V in SE mode, and –2.5 V/V in BTL mode. Thus, the overall gain of the amplifier is −62.5 kΩ/RI in SE mode and −125 kΩ/RI in BTL mode.

This document is a technical manual for the TPA751 audio amplifier. It includes product features such as operating voltage range, supply current, output power, etc.

The UCC35705 and UCC35706 are 8-pin voltage mode primary side controllers with fast over-current protection. These devices are used as core high-speed building blocks in high performance isolated and non-isolated power converters. UCC35705/UCC35706 devices feature a high speed oscillator with integrated feed-forward compensation for improved converter performance. A typical current sense to output delay time of 25 ns provides fast response to overload conditions. The IC also provides an accurate programmable maximum duty cycle clamp for increased protection which can also be disabled for the oscillator to run at maximum possible duty cycle. Two UVLO options are offered. The UCC35705 with lower turn-on voltage is intended for dc-to-dc converters while the higher turn-on voltage and the wider UVLO range of the UCC35706 is better suited for offline applications. The UCC35705/UCC35706 family is offered in 8-pin MSOP (DGK), SOIC (D) and PDIP (P) packages.
