Introduction

TX4144B is a monolithic step-down switching mode converter with integrated power MOSFET. It delivers up to 1.5 A output current over a wide 6 - 60V input voltage range with excellent line and load regulation. The PWM current mode operation ensures easy loop stabilization and fast transient response. An external FS pin allows switching frequency to be set via a single resistor. Protection features include cycle-by-cycle current limiting and thermal shutdown. The device comes in an SOP8 package with minimal external components.
