Flash driver based on STCF01

STEVAL-TLL002V1

Overview

This evaluation board is based on the STCF01, that is a white LED driver optimized for driving two to four LEDs from a Li-Ion battery input.

It provides up to 300 mA over an input voltage range of 2.6 V to 5.5 V and it features 16.5 V output voltage, 1.5 MHz internal power switch, internal soft start, open load voltage protection and optimized internal compensation.
Only an inductor, a Schottky diode, two capacitors and two resistors are required. Besides, a low output ripple is guaranteed by the current mode PWM topology and by the use of low E.S.R. SMD ceramic capacitors The STCF01 is ideal for camera flash in cellular phones requiring, small circuit size and very high efficiency (up to 90%).

Main features

For camera flash in cellular phones
High efficiency over wide range of input voltage from 2.6 V to 5.5 V
PWM mode control
High switching frequency: 1.5 MHz
Output voltage: 16.5 V

Help: Could you guys help me figure out this weird problem? Thanks!
Please advise: #define Uchar8 unsigned char Uchar8 MyRead(Uchar8 ReadId) { Uchar8 Date = 0xff; if(ReadId == 1) { //Code 1 //Code 2 //Code 3 //Date = 3; } return Date; } void Timer0() interrupt 1 using
A filtering algorithm that is very suitable for microcontrollers (with craftsman analysis included)
Craftsman's note: Today I saw a netizen post a filtering algorithm in the forum. At first I thought it was a new algorithm, but after careful analysis, I found that it was a deformation of the first-o

1. This story vividly tells us that we should never get carried away when we succeed2. This reminds me of Deng Xiaoping’s drifting, which should be started from childhood3. If a person is unlucky, the
Can ina226 test negative pressure current?
I was recently working on an ammeter with mA range, and suddenly found that ina226 cannot measure the current under negative voltage? Can TI engineers tell me if there is a way to use ina226 to measur
