Description

TNY178PN is a TinySwitch-II family offline switch IC from Power Integrations. It integrates a high-voltage MOSFET (≈700 V) and the control circuitry in an 8-pin DIP package (PN). Designed for small, low-cost flyback power supplies, it supports direct connecting to rectified mains (85–265 VAC) and provides a simple, low-part-count solution.
Key features:
- 700 V on-chip MOSFET, built-in controller
- Current limit, overvoltage/thermal protection, soft-start
- Fixed-frequency PWM with efficiency-enhancing techniques (e.g., valley switching)
- Primary-side regulation (PSR) with optional opto feedback
- Low standby power and suitable for isolated power supplies in the low-watt range
Typical applications:
- Wall adapters, small chargers, LED drivers, and other isolated offline supplies needing a few watts.

Features

Here are the main features of TNY178PN (TinySwitch-II family):
- Integrated high-voltage MOSFET rated around 700 V with valley switching for high efficiency
- Fixed-frequency current-mode control (typical switching ~65 kHz)
- Primary-side regulation capability (PSR) for regulation without an optocoupler in suitable designs
- Built-in startup current source; no external bias winding required
- Off-line flyback operation with 85–265 VAC input range
- Protective functions: overcurrent/short-circuit with hiccup auto-restart, over-temperature protection
- Low standby power and good efficiency at light loads
- 8-pin DIP package (TNY178PN)
Designed for compact, low-power offline flyback power supplies (a few watts to several watts, depending on transformer design).

Package

TNY178PN comes in an 8-pin DIP (Plastic DIP) package (through-hole).

Pinout

- Pin count: 8 pins (DIP-8/SO-8 package)
- Function: TinySwitch-II offline switcher with an integrated high-voltage MOSFET and control circuitry for flyback converters; provides primary-side regulation (no optocoupler) and current‑mode control for compact switch‑mode power supplies.

Manufacturer

- Manufacturer: Power Integrations.
- What kind of company: A semiconductor company that designs and manufactures high-voltage power conversion and power-management ICs for switch-mode power supplies.

Application

Used in cost‑effective, off‑line isolated SMPS with flyback topology: low‑power AC–DC adapters (wall warts) and chargers, USB power adapters for mobile devices, and small LED‑driver circuits in consumer electronics.
