Part Number: LMR61428
Tool/software:
Dear,
Can I used LMR61428 ic for LCD driver application which is work on 13 Volt 100 mA and input 3.3volt? If not then please suggest me compatible IC to boost 3.3V to 13 Volt at 100 mA.

Part Number: LMR61428 I'm an old-school developer with mostly linear-regulator experience and am looking for tips on picking the right 'boost' switching regulator for a specific project. It needs to take +5V in, either from a wall-wart or a battery, and…
Part Number: LMR61428 Other Parts Discussed in Thread: LMR62014 I have an operating issue that is not covered by the datasheet. I have a variable 7 to 12V in and needs 13.2V out. What current can I expect out?
The LMR61428 should be rated for 2.8A, but…
Looks like your PCB will pass a DRC for netlist connectivity but attempting a SMPS design with a single sided approach is a challenge as you are finding. The ground paths from IC pins 1 and 5 to the input and output capacitors must have the highest priority…
Part Number: LM2623 Other Parts Discussed in Thread: LMR61428 Hello I want too use LMR61428 as an alternate for LM2623. I have found out that the only difference between these parts is the junction to ambient temperature for LM2623 is is 152.5C/W & for…
Part Number: LMR61428 Hi all Would you mind if we ask LMR61428? In case of light load, does LMR61428 operate PFM function? Is it possible to use as fixed PWM function? Kind regards, Hirotaka Matsumoto
