AS1334

The AS1334 is a step-down DC-DC converter designed to power portable applications from a single Li-Ion battery. The device also achieves high-performance in mobile phones and other applications requiring low dropout voltage.
The AS1334 operates from an input voltage range of 2.7 to 5.5V while providing output voltages of 1.2, 1.5, 1.8, 2.5, 3.0 and 3.3V.
Fixed-frequency PWM operation minimizes RF interference. Shutdown function turns the device off and reduces battery consumption to 0.01A (typ.).
The AS1334 is available in a TDFN(3x3) 8-pin package. A high switching frequency (2 MHz) allows use of tiny surface-mount components. Only three small external surface-mount components, an inductor and two ceramic capacitors are required.
