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.
