TPS54350PWPR Datasheet

Switching Converters, Regulators & Controllers


The TPS54350PWPR 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 inchoosing the output filter in ductors and capacitors. The TPS54350PWPR 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. TPS54350PWPR Features • 100 m, 4.5-a peak mosfet switch for high efficiency at 3-a continuous output currentd• Uses external lowside mosfet or dioded• Output voltage adjustable down to 0.891 v with 1% accuracyd• Synchronizes to external clockd• 1805 out of phase synchronizationd• Wide pwm frequency − fixed 250 khz, 500 khz or adjustable 250 khz to 700 khzd• Internal slow startd• Load protected by peak current limit and thermal shutdownd• Adjustable undervoltage lockoutd• 16-pin tssop powerpade package TPS54350PWPR Applications • Industrial & commercial low power systemsd• Lcd monitors and tvsd• Computer peripheralsd
