Boost converter for single-cell battery rails
800 mA switch current and fixed 2.5 V rail
The 800 mA switch current limit is the key parametric for inductor selection. The fixed 2.5 V output eliminates the feedback resistor divider. The 6-DSBGA package keeps the footprint small, but the small balls demand a well-controlled solder paste volume and a stencil with aperture matching the ball diameter.
Active status, no LTB concern
