Boost output circuit diagram with low power dissipation

Published:2011/3/28 21:12:00 Author:Nicole | Keyword: boost output

VT3 is switching regulator; regulator tube VD2 can change potential; VT4 is inverting isolation amplifier; VT4 and its load 33kΩ resistor divide Ui. The two voltage supply for pulse generator circuit. Pulse generator circuit is composed of transformer T and VT1, VT2. This is a non-symmetric self-excited multivibrator of transformer feedback. The power supply of VTl is from 33kΩ resistor, and the current of resistance depends on VT4, VT1, VT2 have different supply voltage, the amplitude of each half weeks of oscillation is proportional changed, the width is inversely proportional changed, the on/off time of VT3 is controled. When the output voltage increases, the differential pair VT6 current of error amplifier increases, VT5 current decreases, the collector potential rises, VT4 current increases, the voltage of 33kΩ resistor voltage drop increases, VT1 supply voltage increases, shortened the on time, shortened the on time of switch VT3. According to the expression of boost output voltage: we can see, the output voltage Uo down to achieve voltage regulation. Conversely, when the output voltage drops, according to the above process to adjust on the opposite, to rise the output voltage, maintaining the output voltage stable. The input voltage is 12 ~ 28V, then the output voltage can be stable for the 30V, maximum output power is 60W, efficiency is 89.4% to 94.7%, instability is ± 0.33%, the output voltage ripple factor is 0.02%, operating frequency is 10kHz.   (View)

LM4911 No-output capacitor(OCL) power circuit diagram

Published:2011/3/23 1:40:00 Author:Rebekka | Keyword: No-output capacitor(OCL), LM4911,

LM4911 No-output capacitor(OCL) power circuit diagram is shown as below. No-output capacitor(OCL) circuit is without the use of squelch control(Mute), because the speed of shutdown control(SD) is faster than squelch control(Mute) at the moment. The noise can be removed after shutdown. The max power dissipation of the no-output power capacitor is PDMAX=4VDD2／π2R.   (View)

LM4916 Single-channel stereo headphone amplifier circuit diagram

Published:2011/3/29 2:44:00 Author:Rebekka | Keyword: LM4916, Single-channel stereo headphone amplifier

LM4916 is a single-channel(SE) stereo headphone amplifier that has 2 Mono differential output audio power amplifiers(Bridge or BTL load) single-ended (SE) stereo headphone amplifier. It is mainly used for mobile phones and other portable audio devices. LM4916 uses 1.5V power supply. Mono BTL model can output 85mW. Mono BTL mode can promote continuous average power into an 8Ω load. Each channel of single-ended (SE) stereo headset can output 14mW and the continuous average power drives 16Ω load. LM4916 uses MM and LLP encapsulation. The user will thanks to its small size. The smallest share of the PCB board space and get the maximum output power. LM4916 reduces switch-off instant noise. It has a external controller, active-low micropower shutdown mode and an internal thermal shutdown protection agency. The pinout of LM4916 is shown as below.   (View)
