Description
The TNY277GN is an energy-efficient offline Switcher incorporates a 700V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry. It uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability. TinySwitch-III combines a high voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator and enables circuit, current limit state machine, 5.85V regulator, BYPASS/MULTI-FUNCTION pin undervoltage, overvoltage circuit and current limit selection circuitry, over-temperature protection, current limit circuit, leading edge blanking. TinySwitch-III incorporates additional circuitry for line undervoltage sense, auto-restart, adaptive switching cycle on-time extension and frequency jitter.

Description
The TNY277GN is a TinySwitch-III which incorporates with a 700V power MOSFET, oscillator, high voltage switched current source, current limit (which is user selectable ) and the thermal shutdown circuitry. The IC uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability. It consist of simple ON/OFF control, no loop compensation is needed. Its lower current limit improves the efficiency in the enclosed adapters or chargers.It also allows optimum TinySwitch-III choice by simply swapping the devices with no other circuit redesign. TinySwitch-III combines with a high voltage power supply MOSFET switch with a power supply controller in one device. Unlike, conventional PWM (pulse width modulators) controllers, it uses a simple ON or OFF control to regulate the output voltage.
Features
● Thermal Shutdown protection
● Output over voltage shutdown with optional Zener
● Line-under voltage detect threshold set using a single optional resistor
● High bandwidth which provides fast turn on with no overshoot and excellent transient load response
● Extended creepage (REFER THE IMAGE) between the Drain and all other pins improves field reliability.
● Enables single sided printed circuit board layout and very low component count enhances reliability,
Pin Configuration
Pin No. | Pin Name | Description |
1 | Enable/under-Voltage | This pin has dual functions : enable input and line under-voltage sense. It also senses line under-voltage conditions through an external resistor connected to the DC line voltage. |
2 | Bypass/Multi-Function | It is the connection point for an external bypass capacitor for the internally generated 5.85 V supply. It also provides a shutdown function, when the current into the by-pass pin exceeds 5.5mA, the devices latches Off until the voltage drops below the voltage of 4.9 V. |
4 | Drain | This pin is the power MOSFET drain connection. It provides internal operating current for both start-up and steady-state operation. |
5,6,7,8 | Source | This pin is internally connected to the output MOSFET source for high voltage power return and control circuit common. |
Applications
● Chargers or adapters for cell-phones, PDAs, digital cameras , MP3 player, trimmers, Bluetooth earphones etc.
● PC standby and other auxiliary supplies
● DVD / PVR and other lower power set top decoders
● Supplies for appliances, industrial systems, metering, etc.
