Übersicht

Description

VIPER20ADIP-E is STMicroelectronics’ off-line switch-mode power-supply IC with an integrated high-voltage MOSFET (about 700 V) in an 8‑pin ADIP package. It is designed for isolated, low‑ to mid‑power AC‑DC supplies (wall-wart adapters, chargers, LED drivers).
Key points:
- Integrated 700 V MOSFET plus current‑mode PWM controller
- Startup current source, undervoltage lockout, overcurrent/overload protection, thermal shutdown
- Often supports primary-side regulation (PSR) to reduce or eliminate opto-isolators
- Pb-free “E” variant; ADIP = 8‑pin DIP package
- Suitable for flyback topologies with compact bill‑of‑materials and moderate switching frequency (tens to low hundreds of kHz)
Use cases: single‑chip solution for low/mid‑power offline supplies. For exact specs (Vds, frequency, current limits, protection behavior) consult the datasheet.

Features

Key features of VIPER20ADIP-E:
- 700 V integrated high-voltage power MOSFET for offline flyback
- Primary-side regulation (PSR) – no opto-isolator required
- Fixed-frequency PWM flyback controller (typical ~110 kHz) with valley switching
- Current-mode control with built-in current limit
- Startup from rectified mains + soft-start
- Protections: short-circuit/overload with hiccup, overtemperature shutdown, UVLO
- Wide input range: 85–265 VAC (rectified)
- High efficiency and low standby power
- Package: DIP-8 (ADIP); -E version typically indicates extended temperature range and lead-free
Designed for compact offline power supplies, adapters, and LED drivers.

Package

VIPER20ADIP-E is in an 8-pin DIP (DIP-8) through-hole package; RoHS-compliant lead-free variant.

Pinout

- Pin count: 8-pin DIP (VIPER20ADIP-E)
- Function: An off-line switch-mode power supply device with an integrated high-voltage MOSFET (≈700 V) and PWM controller for flyback converters. It serves as the primary-side switch in isolated SMPS, with pins for the MOSFET drain/source (primary connection and return), VCC and GND (supply/regulator), and feedback/compensation (FB/COMP or IS) plus enable/protection functions.

Manufacturer

- Manufacturer: STMicroelectronics.
- What kind of company: A multinational semiconductor and electronics company that designs, manufactures, and markets integrated circuits and discrete semiconductors worldwide (headquartered in Geneva, Switzerland).

Application

VIPER20ADIP-E is a high‑voltage offline switcher for isolated flyback converters in low‑power SMPS.
Typical use areas:
- Low‑power offline SMPS for consumer electronics (up to ~20 W)
- Mains adapters, wall warts, USB chargers
- Standby/power‑management supplies for TVs, set‑top boxes, audio, game consoles
- Isolated LED‑driver power supplies (low‑ to mid‑power)
- Small appliances and peripherals needing isolated DC outputs

Equivalent

VIPER20ADIP-E is STMicro’s 650 V offline switch in DIP-8. Direct ST equivalents: VIPER20ADIP (same) and VIPER20A-DIP-8; nearby power-range parts include VIPER22A and VIPER28. External cross-refs: Power Integrations TOPSwitch/TOPSwitch-GX, TinySwitch-II; ON Semiconductor NCP12xx/NCP13xx. Note: pinouts and performance vary—use ST’s cross-reference to confirm exact substitution.
