PW2330 develops a high efficiency synchronous STEP down DC-DC converter capable of delivering3A output current. PW2330 operates over a wide input voltage range from 4.5V to 30V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss. PW2330 adopts the proprietary instant PWM architecture to achieve fast transient responsesfor high STEP down applications and high efficiency at light loads. In addition, it operates atpseudo-constant frequency of 500kHz under continuous conduction mode to minimize the size ofinductor and capacitor

INTRODUCTION In the past, adding speech recording and playback capability to a product meant using a digital signal processor or a specialized audio chip. Now, using a simplified Adaptive Differential Pulse Code Modulation(ADPCM) algorithm, these audio capabilities can be added to any PICmicro device. This application note will cover the ADPCM compression and decompression algorithms, performance comparison of all PICmicro devices, and an application using a PIC16C72 micro-controller.DEFINITION OF TERMS STEP size -value of the STEP used for quantization of ana-log signals and inverse quantization of a number of STEPs.quantization -the digital form of an analog input signal is represented by a finite number of STEPs.adaptive quantization -the STEP size of a quantizer is dramatically changed with time in order to adapt to a changing input signal.inverse quantizer -a finite number of STEPs is converted into a digital representation of an analog signal.
