Module name: Single power supply to dual power supply, SPN Power MoudleVersion: V2.1Release time: November 4, 2019Use power level: s30WIntroductionSPN Power Moudle is a high-efficiency, non-isolated power supply to stop negative power supplyThe output voltage of the conversion module has nothing to do with the input voltage, which can realize automatic step-up and down-voltage in the wide input range of 3~-36V. thisThe module's mountain ground line is in phase with the Han into the ground line, which is especially suitable for integrated operational amplifiers and low-power applications where there is only a single upright system.Differential amplifiers are used in circuits that require positive and negative power supplies.This module is the earliest V0.1 version of the base T and the previous version: the first version of V1.X small batch version, combined with many years of DC-DC circuit design experienceAfter optimizing the topology, changing the PCB layout and layout, and selecting components with excellent performance, it took 4 years to buildInto the V2.1 version.characteristic●Rated output current up to 1AWide input voltage range (3~36V)Circuit efficiency can exceed 90%●Low output ripple and low EMI radiation●Plus or minus 12V and plus or minus 15V can be set by usersEach input/output end meets the 2.54mm pitch, and can be used for J universal board, breadboard, etc.Product parameters:.Structural parameters:Small feet: 49.5x30.5x19 (length x width x height, unit mm):.Weight: about 11.5 gramsElectrical parameters:Input voltage: 3~36VOutput voltage: 12V+0.1V or 15V+0.1VRated output current: 1ACircuit efficiency: up to 91%Light load transmission ripple: about 26mV (100mA load, 20MHz bandwidth)Full load output ripple: about 100mV (1A load, 20MHz bandwidth)Limit parameters:Vw- VcNo: 0~-42VVout←-VevD、VeND -Vour.: 0~ 25VlN: 5A (max).lout+, lour.: 1.25A (max)Module pin definition:Input side:[IN] --Input positive[GND]--Input ground wire (input negative)Output side:[OUT+] --Double power supply positive[OUT-] --Dual power supply negative[GND]---Output ground wire (connected to the negative input mentioned above)Attached:
