DESCRIPTION
With an input voltage range of 2.7V to 5.5V, the EUP3292 is ideal to power portable applications like smart phones, PDAs and other portable equipment. The EUP3292 operates at 2.25MHz fixed switching frequency allowing the use of small inductors and capacitors to achieve a small solution size. Each output supports up to 1A load current, typical. The internal synchronous switch increases efficiency and eliminates the need for an external schottky diode. Automatic switching between PWM low-noise and PFM low-current operation increases efficiency at light loads, further extending battery life. The EUP3292 has internal soft start and avoids inrush current during startup. FEATURES
