The AS1333 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 AS1333 steps down an input voltage of 3.25V to 5.5V to a fixed output voltage of 3.09V.
Fixed-frequency PWM operation minimizes RF interference. Shutdown function turns AS1333 off and reduces battery consumption to 0.01A (typ.).
The AS1333 is available in a 8-pin lead free micro SMD 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.
