Overview
The VIPER16HN is an AC/DC converter from the VIPerPlus family, designed for high-voltage applications with a fixed switching frequency of 115 kHz. It features an 800 V avalanche-rugged power section and supports Buck-Boost and Flyback topologies. The device operates within a temperature range of -40°C to +150°C, drawing a minimum operating supply current of 11.5 V. It delivers up to 9 W output power with a maximum duty cycle of 80% and an output current of 420 mA. Packaged in a DIP-7 through-hole format, it utilizes Si technology and current mode control.
Feature Summary
- Integrates an 800 V avalanche-rugged power section for extended input voltage ranges.
- Features PWM operation with frequency jittering to reduce EMI filter costs.
- Includes hysteretic thermal protection and safe auto-restart after fault conditions.
- Supports self-supply directly from rectified mains, eliminating auxiliary bias windings.
Applications
- Non-isolated SMPS designs
- Home appliances power supplies
- Metering equipment auxiliary power
- High voltage converter circuits
Procurement Notes
Verify the specific suffix 'HN' against the manufacturer's official datasheet to confirm the 115 kHz fixed frequency variant. Ensure the DIP-7 through-hole package matches the PCB footprint requirements. Confirm RoHS compliance status via the official documentation before finalizing procurement orders.
Selection Notes
Select this component for applications requiring direct feedback and energy-saving standby modes below 30 mW at 230 VAC. The 115 kHz frequency is suitable for compact designs where EMI reduction is critical. Consider the 9 W power limit and 420 mA output capability when sizing the transformer and external components for the target application.
Part Context
The VIPER16HN belongs to the VIPerPlus family of energy-saving high-voltage converters by STMicroelectronics. This series integrates power MOSFETs with PWM controllers to simplify off-line converter designs. The HN variant specifically denotes the 115 kHz fixed frequency option, distinguishing it from other frequency variants within the same product line.
