LM3551 LM3552 led driver circuit design

Using the LM3551 and LM3552 are fixed frequency, current mode step-up DC DC converters with two integrated NFETs we can design a very simple and high precision LED brightness control system. The devices are capable of driving loads up to 1A from a single-cell Li-Ion battery.

LM3552 white LED driver

A simple led driver electronic project can be designed using the LM3552 white LED flash driver integrated circuit .
For this led driver electronic project you will need a DC power supply circuit that provide an output voltage between 2.7V and 5.5 volts ( supply voltage must be applied between Vin and GND .

EN jumper connects the “OFF” post to the middle post of the EN header strip. This connects GND to the EN pin of the LM3552, disabling the part.

EL7513 led driver circuit

A very simple white led driver schematic circuit can be designed using the EL7513 constant current boost regulator specially designed for driving white LEDs. It can drive 4 LEDs in series or up to 12 LEDs in parallel or series configuration and achieves efficiency up to 91%.
The brightness of the LEDs is adjusted through a voltage level on the CNTL pin.
This voltage can be either a DC or a PWM signal
