LM2618 400mA Sub-miniature, High Efficiency, Synchronous PWM & PFM Programmable DC-DC Converter
General Description
The LM2618 step-down DC-DC converter is optimized for powering low voltage circuits from a single Lithium-Ion cell.
It provides up to 400mA (300mA for B grade), over an input voltage range of 2.
8V to 5.
5V.
Pin programmable output voltages of 1.
80V, 1.
83V, 1.
87V or 1.
92V allow adjustment for MPU voltage options without board redesign or external feedback resistors.
Internal synchronous rectification provides high efficiency in both PWM and PFM operation.
