PT1203 - Synchronous Step-Down Converter
The PT1203 is a monolithic pulse-width-modulated (PWM) synchronous step-down switch mode regulator with two internal power MOSFETs.
It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation.
Current mode operation provides fast transient response
