Part Number: LM27761 Other Parts Discussed in Thread: LM2775 , TPS63024 , LM27762 Hello,
Can LM27661 uses at inverting buck-boost operation?
My Customer is considering by LM27761 at Specification of the following described.
Vin : 2.5~4.2V (Li-Ion…
Part Number: LM27761 Hello
I was trying to figure out the power dissipation of the LM27761 in our circuit. For our design, VIN = +5.5V, Vout = -2.5V and Iout = 62mA
In the datasheet, PD = PIN – POUT = [VIN × (–IOUT + IQ) – (VOUT × IOUT)]
= [+5.5V…
Part Number: LM27761 We need something which can limit o/p current of the negative regulator LM27761 (-3.5V) to 10mA after 10mA current should not increase.
Part Number: LM27761 Hi, Could you tell me about negative output circuit? Please confirm the attached file. LM27761.pdf
Is this configuration feasible? if you have any concerns, please let me know. Best Regards, Yusuke/Japan Disty
Part Number: LM27761 Hey,
in the past (with non inverting DC-DCs) i have used the bellow configuration to achieve a tunable output and it worked fine. when the DAC outputs 0 R3 is in parellel to R2 yielding a "new" output value, when the DAC voltage…

LM27761 negative voltage converter has an excellent performance but the WSON-8 package is tiny for trial PCB (i mean that the device will be soldered with hot air at workbench…
Other Parts Discussed in Thread: LM27761 Our customer consider to use LM27761DSGT.
They found problem that is input current increase at high temperature and at no load conditon.
Input current
25 degreeC : 0.4mA
over 68degreeC:5mA
They would…
Other Parts Discussed in Thread: LM27761 Hi Team,
I understand that LM27761 have the output discharge function.
However, I can’t find the discharge resistor value in the datasheet.
Could you please let me know if you have any information of that…
Other Parts Discussed in Thread: LM27761 Hi
I have a board using the LM27761 and I followed the recommendation for a flying capacitor of between 470nF and 1uF and placed a 1uF but this does not charge the capacitor up properly on my board. I found…
