TEA1755規(guī)格書詳情
1.2.1 Key features
? PFC and flyback controller integrated in one SO16 package
? Switching frequencies of PFC and flyback controller are independent of each other
? No external hardware required for the communication between both controllers
? High level of integration, resulting in a low external component count
? Integrated mains voltage enable and brownout protection
? Fast-latch reset function implemented
? Power-down functionality for very low Standby mode power requirements
1.2.2 System features
? Safe restart mode for system fault conditions
? High-voltage start-up current source (5 mA)
? Reduction of HV current source (1 mA) in safe restart mode
? Wide VCC range (13.4 V to 38 V)
? MOSFET driver voltage limited
? Easy control of start-up behavior and VCC circuit
? General-purpose input for latched protection
? Internal IC overtemperature protection
? Accurate PFC switch on/switch off control using flyback switching frequency
measurement
? One high-voltage spacer between the HV pin and the next active pin
? Open pin protection on the VINSENSE, VOSENSE, PFCAUX, FBCTRL, and FBAUX
pins
1.2.3 PFC features
? Dual-output voltage boost converter
? QR/DCM operation with valley switching
? Frequency limitation (139 kHz) to reduce switching losses and ElectroMagnetic
Interference (EMI)
? ton controlled
? Mains input voltage compensation for control loop for good transient response
? OverCurrent Protection (OCP)
? Soft-start and soft-stop
? Open/short-circuit detection for PFC feedback loop: no external OverVoltage Protection
(OVP) circuit necessary
? Adjustable delay for switching off the PFC
? Overriding the PFC switch on/switch off functionality
1.2.4 Flyback features
? Burst/FR/QR/DCM operation with valley switching
? Frequency Reduction (FR) with an adjustable minimum peak current and valley
switching to maintain high efficiency at low output power levels
? Burst mode enhances the overall efficiency at low-output power
? Burst mode benefits the reduction of audible noise
? Frequency limitation (130 kHz) to reduce switching losses and EMI
? Current mode controlled
? Overcurrent protection
? Soft-start
? Accurate OVP through auxiliary winding
? Time-out protection for output overloads and open feedback loop, available as safe
restart (TEA1755T) or latched (TEA1755LT) protection
? VCC undervoltage prevention during burst mode
