The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium- ...

Low-power Solution for DSP Intensive Audio Applications

1．Describe a Θ(n lg n)-time algorithm that, given a set S of n integers and another integer x, determines whether or not there exist two elements in S whose sum is exactly x. (Implement exercise 2.3-7.) #include<stdio.h> #include<stdlib.h> void merge(int arr[],int low,int mid,int high){   ...

Lithium–sulfur batteries are a promising energy-storage technology due to their relatively low cost and high theoretical energy density. However, one of their major technical problems is the shuttling of soluble polysulfides between electrodes, resulting in rapid capacity fading. Here, we present ...

void IIC_Init(void) {                             //由于STM8单片机，可以在输入和输出条件下读取IO口状态，故直接设置为输出。     GPIO_Init(IIC_SCL_PORT, IIC_SCL_PIN, GPIO_MODE_OUT_OD_HIZ_SLOW );     GPIO_Ini ...
