The STR-A6153E is a power integrated circuit (IC) from Sanken Electric Co., Ltd. It is a multi-channel PMIC for AC-DC Converters, Offline Switchers and Switching Regulators. It is available in a variety of packages, ranging from 6-pin SOP to 42-pin QFP, and is suitable for applications ranging from high density bipolar power supplies to DC high voltage regulated power supplies.

The STR-A6153E is a power mosfet and management IC designed with advanced technologies that enable it to provide superior efficiency in AC-DC converters, offline switchers and switching regulators. It contains an on-board MOSFET, an intelligent control circuit, PWM Modulator, and power supply EMC filter. The MOSFET provides high current capability in a single-package, while the control circuit has the intelligence to reduce line and load power losses by maintaining the optimal conduction angle and optimally allocating switching times to minimize switching losses.

The Chip also has an advanced PWM modulator and a power supply EMC filter. The PWM modulator provides an easily programmable operation to generate the desired output waveforms and to reduce the rumble noise and harmonics in the output waveforms. The power supply EMC filter suppresses noise generated by the IC, ensuring compliance with the EMC regulation. The STR-A6153E features an integrated soft start for current start-up, a VCC under-voltage lockout and short-circuit protection.

The usage of the STR-A6153E is mainly to create a DC voltage supply from an AC source. The output of the circuit is fully regulated, which means the output voltage is always the same and independent of any load variation regardless of the AC source parameters. This is done by means of Pulse Width Modulation (PWM) technology, which uses a MOSFET as the output HF power stage.

The STR-A6153E operates in fixed-frequency. The frequency of the PWM can be adjusted depending on the design requirements. The control loop monitors the output voltage via an internal voltage divider and provides the references to the PWM control loop. During the on-time period of the switching cycle, the PWM control loop applies the necessary duty cycle to the MOSFET so as to provide the necessary level of output voltage.

The MOSFET also acts as a low-pass filter, removing high-frequency components from the output voltage and creating the pure DC output. In addition, the STR-A6153E contains a soft start circuitry to prevent overshoot in the output voltage at power up. The power supply EMC filter also helps to reduce the conducted and radiated emissions.

In summary, the STR-A6153E is a multi-channel power integrated circuit specially designed for AC-DC Converters, Offline Switchers and Switching Regulators applications. The power integrated circuit contains an on-board MOSFET as well as an intelligent control circuit, PWM Modulator and a power supply EMC filter. All these components work together to regulate the output voltage, reduce switching losses, and reduce high frequency electromagnetic emissions from the power supply.
