TPS54354 

A 4.5V to 20V input, 1.8V output, 3A synchronous buck converter with low-side FET gate drive

illustrate   The TPS5435x is a medium-sized output current synchronous step-down PWM converter with an integrated high-side MOSFET and an optional low-side gate drive external MOSFET. Features include a high-performance voltage error amplifier for maximum performance under transient conditions. The TPS5435x has an undervoltage latch circuit that prevents start-up until the input voltage reaches a predetermined value; Internal slow-start circuitry to limit inrush current, as well as a power supply good output to indicate effective output conditions. The synchronization function is not configured as an input or output to facilitate 180° out-of-phase synchronization. The TPS5435x device features a thermally enhanced 16-pin TSSOP (Works) PowerPAD™ package.   characteristic   100 mOhm, 4.5 – A high-efficiency MOSFET with a peak of 3 consecutive output switching currents Use an external MOSFET or diode Lowside Fixed Output Versions - 1.2V/1.5V/1.8V/2.5V/3.3V/5.0V Internally compensates for low component counts to external clock synchronization 180° out-of-phase synchronization Wide PWM frequency - fixed 250 kHz, 500 kHz or adjustable to 700 kHz to 250 kHz Slow start inside Protect the load by peak current limiting and thermal shutdown Adjustable undervoltage lockout The 16-pin TSSOP packages the PowerPAD™ apply Industrial and commercial low-energy systems LCD and television Computer peripherals High-performance DSP, FPGA, ASIC, and microprocessor regulations for the point of load
