Overview
The VIPER12ADIP-E is an off-line switcher from the VIPerPlus family, integrating a high voltage power MOSFET and current mode PWM controller in a DIP-8 package. It operates with a fixed switching frequency of 60 kHz and supports a VDD supply range of 9 V to 38 V. The device delivers up to 13 W output power at European input voltages (195-265 Vac) and features a 730 V breakdown voltage. It includes automatic burst mode for low load conditions and overvoltage protection in HICCUP mode.
Feature Summary
- Integrates a dedicated current mode PWM controller with a high voltage power MOSFET on a single silicon chip.
- Features automatic burst mode operation to minimize input power consumption under light load conditions.
- Includes comprehensive protection mechanisms such as overtemperature, overcurrent, and overvoltage protection with auto-restart capabilities.
Applications
- Battery charger adapters
- Standby power supplies for televisions or monitors
- Auxiliary supplies for motor control systems
Procurement Notes
Verify the specific suffix 'E' indicates RoHS compliance and lead-free status as per STMicroelectronics standards. Confirm the DIP-8 through-hole packaging matches your PCB design requirements. Ensure the 60 kHz switching frequency aligns with your EMI filtering strategy. Check that the 13 W power capability meets your system's maximum load demands under specified operating temperatures.
Selection Notes
Select this component for applications requiring a compact, integrated AC/DC solution with minimal external components. The wide VDD voltage range accommodates auxiliary supply variations, making it suitable for battery charger configurations. Consider the DIP-8 package for through-hole assembly needs. Evaluate the 60 kHz fixed frequency against potential EMI constraints compared to jittering frequency alternatives.
Part Context
This part belongs to the VIPerPlus family, which combines high-voltage MOSFETs with advanced PWM controllers. The VIPER12A variant specifically targets low-power offline SMPS applications. The DIP-8 package provides robust thermal performance and ease of manual assembly compared to surface-mount options.
Replacement Considerations
The VIPER12A-E series serves as the base family. Verify pin compatibility if substituting with other VIPerPlus variants like VIPER22A or VIPER53A, noting differences in power capability and package types.
