TPS54350-EP 具有集成 Fet 的增强型产品 4.5V 至 20V 输入 3A 输出的同步 Pwm 转换开关

The TPS54350 is a medium output current synchronous buck PWM converter with an integrated high side MOSFET and a gate driver for an optional low side external MOSFET. Features include a high performance voltage error amplifier that enables maximum performance under transient conditions and flexibility in choosing the output filter inductors and capacitors. The TPS54350 has an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 4.5 V; an internal slow-start circuit to limit in-rush currents; and a power good output to indicate valid output conditions. The synchronization feature is configurable as either an input or an output for easy 180° out of phase synchronization.

The TPS54350 device is available in a thermally enhanced 16-pin TSSOP (PWP) PowerPAD™ package
