TEA1833TS规格书详情
General description
The TEA1833TS is a low-cost switched-mode power supply (SMPS) controller IC
intended for flyback topologies. The TEA1833TS operates in peak current and frequency
control mode. Frequency jitter has been implemented to reduce electromagnetic
interference (EMI). Slope compensation is integrated for continuous conduction mode
(CCM) operation.
The TEA1833TS IC features overpower protection (OPP). The controller accepts an
overpower situation up to 200 for a limited time.
Mains undervoltage protection (brownin/brownout), output overvoltage protection (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 22 of the maximum peak
current. To limit the switching losses, the switching frequency is reduced. 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 TEA1833TS makes the design of low-cost, highly efficient, and reliable supplies
easier by requiring a minimum number of external components. The device is especially
suited for medium power applications.
Features and benefits
• SMPS controller IC enabling low-cost applications
• Wide input voltage range (10.5 V to 36 V)
• Integrated overvoltage protection (OVP) on the VCC pin
• Accurate overvoltage protection (OVP) via the ISENSE pin
• Dedicated burst mode, allowing a low VCC capacitor value
• Very low supply current during start-up and restart (11 μA typical)
• Low supply current during normal operation (0.58 mA typical without load)
• Adaptive internal overpower timeout
• Overpower protection including high/low line compensation
• 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
• Peak power operation up to 200 by frequency increase and peak current increase
• Slope compensation for CCM operation
• Limitation of switching frequency at high mains to reduce the maximum drain voltage
• Integrated soft start
• Drive capability 300 mA source, 750 mA sink
• Maximum duty cycle set at 90
• Mains undervoltage protection (brownin/brownout)
• Output short-circuit protection (OSCP), avoiding transformer saturation
• External overtemperature protection (OTP)
• IC overtemperature protection
• Internal VCC OVP, external OVP, internal OTP, and external OTP are latched
protections; all other protections cause a restart
Applications
• All applications that require an efficient and cost-effective power supply solution. The
TEA1833TS is especially suited for medium power applications.
TEA1833TS属于集成电路(IC) > AC DC 转换器,离线开关。恩智浦半导体公司制造生产的TEA1833TSAC DC 转换器,离线开关该系列是元器件级控制产品,用于构建将交流市电转换为直流电(通常电压大幅降低)的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比,以及此类系统中通常需要隔离,这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途,但也有许多专门用于此用途的库存产品,请参见“开关转换器,SMPS 变压器”标题。
