1.5v to 5v boost

Fragrance
I think 1V0 input might be too low for TPS61042
and 30v0 too high for output:

Vin(Min)(V) 1.8
Vin(Max)(V) 6
Type Inductive
LED(#) 6
LED Configuration Series
Switch Current Limit(Typ)(A) 0.5
Over-Voltage Protection(Min)(V) 28
Peak Efficiency(%) 85
Iq(Typ)(mA) 0.038
Shutdown Current(Typ)(uA) 0.1
Switching Frequency(Max)(kHz) 1000
Topology Boost
Iout(Max)(A) 0.03
Operating Temp Range(Celsius) -40 to 85
Pin/Package 8SON

how can i drop 1 volt from 5 volts?

Hi, No problem. I even boosted 0.2 Volts to 8 Volts DC at 30mA, with simple components no SMPS IC's or something like that.

Could you please give more details of your design, including cirucit diagram and may be some construction details.

I had built 1.5V to 5V booster with transistors but cannot get more than 20mA.

booster 2,5 volt

Hi,

I used the following components:

BSS138 N-MFET
Coil of 220uH
and 22uF Capacitor.
Diode low drop fast type any will do. Vt=0.23 V

I used a frequency of 1 MHz and dc of 60- 80 %.

Normal step-up topologie

regards,

Paul.
