EUP2573 1.2MHz Step-Up PWM Controller DESCRIPTION The EUP2573 is a compact, high efficiency, fixed frequency pulse-width-modulation (PWM) controller. It provides an easy-to-use power supply solution for the application from one Li-ion battery to 5V output. All compensation and protection circuitry are integrated to minimize external components. The 1.2MHz high switching frequency allows smaller inductor and output capacitor, making the EUP2573 ideally suited for small battery-powered applications and saves PCB space. The EUP2573 contains thermal shutdown function and output short protection circuit. Built-in soft-start circuitry prevents excessive inrush current during start-up. The EUP2573 is available in a Pb-free, thin-SOT23-5 package. FEATURES VDD Range: 2.7V to 5.
