DESCRIPTION
With an input voltage range of 2.7V to 5.5V, the EUP3402 is ideal to power portable applications like smart phones, PDAs and other portable equipment. The EUP3402 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. The EUP3402 has a user selectable mode of forced PWM and PFM/PWM mode. The forced PWM mode operation provides the lowest ripple noise and the PFM mode operation provides high efficiency at light loads. The EUP3402 has internal soft start and avoids inrush current during startup. When shutdown, internal resistor discharges the output capacitor. FEATURES
