PROBLEM TO BE SOLVED: To provide a power supply, an onboard electronic system, a control program of a booster circuit, and a control method of the booster circuit making it possible to realize a compact and lightweight design.SOLUTION: A power supply 140 in accordance with the present invention is mounted in a vehicle whose engine can be started with power fed from a battery. The power supply 140 includes a booster 200 capable of boosting a voltage fed from the battery, detection means that detects start of an engine, count means that counts the number of times, by which the engine is started, according to the detection means, and a control unit 220 that controls the booster 200. When the number of times, by which the engine is started, provided by the count means within a timer period does not exceed a permissible number of times N, the control unit 220 outputs a control signal S1, which permits boosting by the booster 200, in response to engine start. |
