POWER INTEGRATIONS TNY 285DG - AC/DC offline switch, 85-265 VAC, 11W, SMD-8B-7

Description

Power(max): 11 W
Breakdown Voltage: 725
Output Profile: CV

With the mains-compensated overload protection, the TinySwitch 4 devices drastically reduce the maximum overload fluctuation over the entire input voltage range. This is particularly useful in applications such as PC standby and CV adapters for limiting the maximum output power during the overload fault condition.

The TinySwitch-4 also includes a 725V MOSFET that easily enables 80% de-rating in high reflected voltage and high bus voltage designs. The BP/M pin allows the MOSFET current limit to be adjusted up or down, allowing designers to optimize power output and efficiency in a variety of physical implementations. An on-time extension function extends the low-line regulation range so that the hold-up time can be maintained even at lower values of input capacitance.

• MOSFET with 725 V rated voltage
• Increases the BV derating margin
• Mains-compensated overload power - no additional components
• Drastically reduces the maximum overload fluctuation over the universal input voltage range
• ±5% switch-on threshold for UV: detection of mains voltage with a single external resistor
• Simple ON/OFF control, no loop compensation required
• Selectable current limiting by BP/M capacitor value
• Enables optimal TinySwitch 4 selection by replacing components without further circuit redesign
• Tight I2f parameter tolerance reduces system cost
• Maximizes the use of MOSFETs and solenoids
• Extended duty cycle - extends low line regulation range/hold-off time to reduce input capacitance
• Self-biased: no bias winding or biasing components
• Frequency jittering reduces the cost of EMI filters
