TEXAS INSTRUMENTS LM3477AMM 控制器, 高压侧, N通道, 用于开关稳压器, 35V-2.97V电源, 500 kHz, 200mA输出, MSOP-8
The is a high-side N-channel MOSFET Switching Regulator Controller can be used in topologies requiring a high side MOSFET such as buck, inverting buck-boost and zeta regulators. Its internal push pull driver allows compatibility with a wide range of MOSFETs. This, the wide input voltage range, use of discrete power components and adjustable current limit allows controller to be optimized for a wide variety of applications. It uses a high switching frequency of 500kHz to reduce the overall solution size. Current-mode control requires only a single resistor and capacitor for frequency compensation. The current-mode architecture also yields superior line and load regulation and cycle-by-cycle current limiting. A 5µA shutdown state can be used for power savings and for power supply sequencing. Other features include internal soft-start and output over voltage protection.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
