Overview
The VIPer100-E, produced by STMicroelectronics, is a high-performance SMPS (Switch-Mode Power Supply) primary IC that integrates a state-of-the-art PWM circuit and a high-voltage Vertical Power MOSFET on the same silicon chip. This device is part of the VIPower M0 Technology and is designed for offline power supplies, offering a range of features that enhance efficiency, reliability, and safety.
It supports adjustable switching frequencies up to 200 kHz, current mode control, soft start and shutdown control, and automatic burst mode operation in stand-by conditions. The VIPer100-E is particularly suited for applications requiring low standby power consumption, such as those needing to meet the German 'Blue Angel' norm of less than 1W total power consumption in standby mode.

Q & A
- What is the maximum drain-source voltage of the VIPer100-E?
The maximum drain-source voltage (VDS) is 620V.
- What is the typical switching frequency range of the VIPer100-E?
The switching frequency can be adjusted up to 200 kHz.
- Does the VIPer100-E support burst mode operation?
Yes, it supports automatic burst mode operation in standby conditions to meet low power consumption standards.
- What is the purpose of the UVLO feature in the VIPer100-E?
The UnderVoltage Lock-Out (UVLO) feature protects the device against low voltage conditions by shutting it down when the supply voltage drops below a certain threshold.
- How does the VIPer100-E handle over-temperature conditions?
The device has an over-temperature protection feature that shuts it down when the junction temperature exceeds a certain limit (typically 170°C) and restarts when the temperature decreases.
- Can the VIPer100-E be synchronized with an external clock?
Yes, the OSC pin provides a synchronization capability when connected to an external frequency source.
- What is the maximum current handling capability of the VIPer100-E?
The maximum current is internally limited, but the device can handle up to 3A of continuous current.
- How does the soft start feature work in the VIPer100-E?
The soft start feature reduces stress on components during startup by gradually increasing the output voltage and current, which can be implemented using a capacitor on the COMP pin.
- What is the typical power dissipation of the VIPer100-E at 25°C?
The typical power dissipation at 25°C is 82W.
