30W +- 1.2V 3.3V 5V 9V 12V 15V Positive & Negative Dual Output Power Supply DC DC Step-down Buck Converter Module DC 5.5-32V

Descrtion: 1: Wide range of applications 2: A variety of voltage specifications to choose from 3: Small size 4: Maximum output power 30W 5: Simple to use Module name: TPS5430 to positive and negative voltage output module Input voltage: 5.5-32V Output voltage: plus or minus 1.2V, plus or minus 3.3V, plus or minus 5V, plus or minus 9V. plus or minus 12V. plus or minus 15V (input voltage must be higher than the output voltage 2v or more) Maximum output current: positive voltage 3A, negative voltage 2A Input and output preure difference: 2v Maximum output power: 30w Static power consumption: 16mmA (measured at 12V input,) Working frequency: 500KHZ Output rple: 30mV at 5V. 60MV at negative 5V, (for reference only) Module weight: 20g Module size: 55*30*20mm Wiring method: transfer PIN. "Send transfer wiring, 2PIN and 3PIN each) The main features of the module are as follows: (1) The module realizes the DC-DC step-down conversion function, single power supply input, positive and negative power supply output, designed and produced according to the official data manual. (2) Input DC voltage range: 6V~32v, output DC voltage: ±5V, ±9V, ±12V or ±15V versions are optional, that is, to realize the function of converting the positive voltage of a single power supply into positive and negative voltages. The input voltage must be at least about 1V greater than the output voltage. According to the official data sheet, the input voltage can reach up to 36V in theory, but it is recommended that the input voltage should not exceed 30V. When the output is under heavy load, it is recommended that the input voltage be greater than 6V. (3) Maximum output current: 3A. According to the official data sheet, the theoretical value of the output current can reach 3A, but the ch will heat up very seriously, and the output voltage rple will also increase, so when the power used exceeds 2OW, please add a heat sink to the TPS5430 ch for heat diation. Otherwise, the output voltage will be unstable, the output power rple will become larger, and the ch may even be burned. The default output voltage of the module is ±5V, and the recommended maximum output current is 2A. (4) Ultra-low output DC voltage rple: when the input voltage is 12V, when the output is no-load, the ±5V output voltage rple is lower than 30mvpp; when the output is connected to a 10Ω load, the +5V output voltage terminal has low rple At 50mVpp, the -5V output voltage rple is lower than 75mVpp. (5) Ultra-low load regulation rate: The output load regulation rate is le than 5%. (6) Module efficiency: The greater the input voltage, the lower the power output efficiency; the power supply efficiency will also become lower as the load becomes smaller; the efficiency of the negative voltage terminal is lower than that of the positive voltage terminal. Precautions: 1 Input has no re connection protection, it is forbidden to re the positive and negative input of the input, the re connection will burn the module 2 The input voltage must be more than 1V higher than the output voltage Package included: 1*TPS5430 to positive and negative voltage output module 2*Terminal wire
