AMC1200 pinout

Description

The AMC1200 and AMC1200B are precision isolation amplifiers with an output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide galvanic isolation of up to 4250 V PEAK (AMC1200B) or 4000 V PEAK (AMC1200) according to UL1577 and IEC60747-5-2.

Used in conjunction with isolated power supplies, these devices prevent noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry.

The input of the AMC1200 or AMC1200B is optimized for direct connection to shunt resistors or other low voltage level signal sources. The excellent performance of the device supports accurate current control resulting in system-level power saving and, especially in motor-control applications, lower torque ripple. The common mode voltage of the output signal is automatically adjusted to either the 3-V or 5-V low-side supply.

The AMC1200 and AMC1200B are fully specified over the extended industrial temperature range of –40°C to 105°C and are available in a wide-body SOIC-8 package (DWV) and a gullwing-8 package (DUB).

Description

This is 40V, 0.2A 300KHz PWM controller.

The TL494 device incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application.

The TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.
