PT1204 3A, 18V, 350KHz Synchronous Step-Down Converter GENERAL DESCRIPTION The PT1204 is a monolithic pulse-width-modulated (PWM) synchronous step-down switch mode regulator with two internal power MOSFETs. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown. The PT1204 requires a minimum number of external components, available in ESOP-8 package.
