世纪芯较早就已经顺利取得技术突破,成功破解多款典型IC芯片,而由于解密难度大、周期长,使得解密成本及费用相对较高。为此,世纪芯又专门组织技术力量进行该系列芯片低成本解密方案研究,使针对TEA1733AT芯片解密的技术更为成熟,解密成本更低,为客户实现更大经济效益。这里,我们仅以TEA1733AT芯片为例,针对其性能特征做简单介绍:
The TEA1733AT is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in fixed frequency mode. Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI)。 Slope compensation is integrated for Continuous Conduction Mode (CCM) operation.The TEA1733AT IC includes OverPower Protection (OPP)。 This enables the controller to operate under overpower situations for a limited amount of time.Two pins, VINSENSE and PROTECT, are reserved for protection purposes. Input UnderVoltage Protection (UVP) and verVoltage Protection (OVP), output OVP and OverTemperature Protection (OTP) can be implemented using a minimal number of external components.At low power levels the primary peak current is set to 25 % of the maximum peak current and the switching frequency is  reduced to limit switching losses. The combination of fixed frequency operation at high output power and frequency reduction at low output power provides high-efficiency over the total load range.The TEA1733AT enables low cost, highly efficient and reliable supplies for power requirements up to 75 W to be designed easily and with a minimum number of external components.
Features
·SMPS controller IC enabling low-cost applications
·Large input voltage range (12 V to 30 V)
·Very low supply current during start-up and restart (typically 10 μA)
·Low supply current during normal operation (typically 0.55 mA without load)
·Overpower or high/low line compensation
·Adjustable overpower time-out
·Adjustable overpower restart timer
·Fixed switching frequency with frequency jitter to reduce EMI
·Frequency reduction with fixed minimum peak current to maintain high-efficiency at low output power levels
·Slope compensation for CCM operation
·Low and adjustable OverCurrent Protection (OCP) trip level
