TFS7707H集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器規(guī)格書PDF中文資料

Product Enhancements

? Selectable 132 kHz main switching frequency for lower cost

and smaller magnetics

? Increased main peak power vs. HiperTFS-1

? Self-biased high-side driver eliminates high-side bias winding

and diode

? Package lead form and pinout modified for easier insertion and

PC-board layout

? Tighter UV(ON) standby threshold tolerance

? Improved standby no-load performance

Key Benefits

? Single IC solution for two-switch forward main (66 kHz/132 kHz)

and flyback (132 kHz) standby

? High integration allows smaller form factor and higher power

density designs, with reduced component count

? Incorporates control, gate drivers, and three power MOSFETs

? Level shift technology eliminates need for pulse transformer

? Protection features include: UV, OV, OTP, OVP, standby OPC,

SCP, and ILIMIT

? Transformer reset control, prevents saturation under all conditions

? Main duty cycle operation above 50 for reduced rms currents

and lower output diode voltage rating

? Less than 10 variation in standby overload power over input

voltage range

? Up to 586 W peak output power in a highly compact package

? >90 efficiency at full load

? Simple clip mounting to heat sink without need for insulation pad

? Halogen free and RoHS compliant

Typical Applications

? PC (80 PLUS? Bronze and 80 PLUS Silver)

? Printer

? LCD TV

? Video game consoles

? High-power adapters

? Industrial and appliance
