Product detail
Product description:

TNY284-290 is a high-efficiency off-line switching power management chip with a line compensation overload power supply in the SOP7 package.

Product highlights:

1) Lowest system cost with enhanced flexibility

• 725 V rated MOSFETs

• Increased BV derating margin

• Line Compensated Overload Power – No Additional Components Required

• Significantly lower maximum overload change over universal input voltage range

• ±5% Turn-On UV Threshold: Sense Line Voltage Using Single External Resistor

• Simple on/off control without loop compensation

• Current Limit Selectable by BP/M Capacitor Value

• Higher current limit extends peak power, or in open frame applications, maximum continuous power

• Lower Current Limit Improves Enclosed Adapter/Charger Efficiency

• Optimal TinySwitch™-4 selection by switching devices without additional circuit redesign

• Tight I2f parameter tolerance reduces system cost

• Maximizes the utilization of MOSFETs and magnetics

• Extended on-time – extends low-line regulation range/hold-up time to reduce input bulk capacitance

• Self-Biasing: No Bias Winding or Biasing Components

• Frequency dithering reduces EMI filter cost

• Pin layout simplifies PCB thermal dissipation

• SOURCE pin is electrically quiet for low EMI


2) Enhanced Security and Reliability Features

• Accurate hysteretic thermal shutdown protection with auto-recovery requires no manual reset

• Auto-restart provides <3% of maximum power under short-circuit and open-loop fault conditions

• Optional Zener diode output overvoltage shutdown

• Fast AC reset with optional UV external resistor

• Low component count improves reliability and supports single-sided PCB layout

• High bandwidth provides fast turn-on without overshoot and excellent transient load response

• Extended creepage between DRAIN and all other pins improves field reliability

3) EcoSmart™ - extremely energy efficient

• Easily meets all global energy efficiency regulations

• <30 mW no load with bias winding, <150 mW at 265 VAC without bias winding

• ON/OFF control provides constant efficiency down to very light loads

– Ideal for mandatory CEC regulations and EuP standby requirements
