VIPER01数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The device is a high voltage converter smartly integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows the extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced. This IC meets the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation under light load. The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense-FET, error amplifier and oscillator with jitter allow a complete application to be designed with the minimum number of components.

特性 Features

• 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered
• Embedded HV startup and sense-FET
• Current mode PWM controller
• Drain current limit protection (OCP)
• Wide supply voltage range: 4.5 V to 30 V
• Self-supply option allows the auxiliary winding or bias components to be removed
• Minimized system input power consumption:
•Less than 10 mW @ 230 VAC in no-load condition
•Less than 400 mW @ 230 VAC with 250 mW load
• Jittered switching frequency reduces the EMI filter cost:
•30 kHz ± 7% (type X)
•60 kHz ± 7% (type L)
•120 kHz ± 7% (type H)
• Embedded E/A with 1.2 V reference
• Protections with automatic restart: overload/short-circuit (OLP), line or output OVP, max. duty cycle counter, VCC clamp
• Pulse-skip protection to prevent flux-runaway
• Embedded thermal shutdown
• Built-in soft-start for improved system reliability

简介

VIPER01属于集成电路（IC）的ACDC转换器离线开关。由制造生产的VIPER01AC 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。
