描述 The LM5032 dual current mode PWM controller contains all the features needed to control either two independent forward dc/dc converters or a single high current converter comprised of two interleaved power stages. The two controller channels operate 180° out of phase thereby reducing input ripple current. The LM5032 includes a startup regulator that operates over a wide input range up to 100 V and compound (bipolar + CMOS) gate drivers that provide a robust 2.5-A peak sink current. The adjustable maximum PWM duty cycle reduce stress on the primary side MOSFET switches. Additional features include programmable line undervoltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable response time, PWM slope compensation, soft-start, and a 2-MHz capable oscillator with synchronization capability. For all available packages, see the orderable addendum at the end of the datasheet. 特性 Two Independent PWM Current Mode Controllers Integrated High-Voltage Startup Regulator Compound 2.5-A Main Output Gate Drivers Single Resistor Oscillator Setting to 2 MHz Synchronizable Oscillator Programmable Maximum Duty Cycle Maximum Duty Cycle Fold-Back at High-Line Voltage Adjustable Timer for Hiccup Mode Current Limiting Integrated Slope Compensation Adjustable Line Undervoltage Lockout Independently Adjustable Soft-Start (Each Regulator) Direct Interface with Opto-Coupler Transistor Thermal Shutdown TSSOP 16-Pin Package 相关终端应用 (10) Drone Accessories 交流逆变器和 VF 驱动器 制造机器人 可再生能源存储 - 锂聚合物电池管理器 工业 AC-DC 无刷直流电机驱动器 物料搬运(叉车、仓库机器人等) 电动交通工具(电动自行车、电动滑板车和电动汽车) 电器电池充电器 Iczoom拍明芯城(www.iczoom.com)聚焦于中小企业需求,具有货源可靠、品类齐全、交付及时、价格实惠、方案众多的特点和服务优势,客户来源非常丰富,原厂、代理商、正品经销商、同行电商、终端商均有注册。 Iczoom拍明芯城严格把控卖家资质和货品质量,快速匹配买卖信息,帮助客户“卖得快、买得全”。同时,Iczoom拍明芯城为中小企业提供专业的管理软件和全程供应链服务,让客户轻松实现内部的数据化管理。 |
