From the project

Power system design for a small robot: a Re22 relay (9 V coil) and an HC-SR04 ultrasonic sensor (5 V), both fed from a 3S Li-ion battery (12.6 V full charge).

Power system design for a small robot: a Re22 relay (9 V coil) and an HC-SR04 ultrasonic sensor (5 V), both fed from a 3S Li-ion battery (12.6 V full charge).

The pack is always above both target voltages, so both rails are step-down. Reverse-polarity protection is needed since the battery connects through a separable connector.

- Both rails: buck (step-down) converters, not LDOs. At full charge an LDO wastes power as heat for no benefit; near end-of-discharge the 9 V rail has too little headroom for typical LDO dropout. A buck stage stays efficient (>90%) across the full battery swing. -…
