Automotive front-end power supply that delivers 16W output to a 12V vehicle battery. The first stage is a pre-boost LM5150-Q1 to maintain a regulated mid-rail voltage of 8.5V during cold-crank operati
1. E53_SF1 expansion board and its driverabout E53 standard interfaceThe E in the E53 interface standard is taken from the first letter of the English word "Expansion". The size of the board is 5×3cm,
The main function I want to achieve is to use a single lithium battery to power the system, and then use TPS61200 to stabilize the voltage to 3.3V. During the test, a voltage regulator was used to sim
Last time, I successfully made a low-power (15W) flyback switching power supply for mass production, which greatly increased my confidence. This time, I made a higher-power (=50W) flyback switching po
