Description

The STR-W6200D series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package. Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components.

A PWM Off-Line Switching Regulator is a type of power supply or voltage regulator that operates as an offline switch-mode power supply (SMPS) and uses pulse-width modulation (PWM) to control the output voltage. These regulators are commonly used in a wide range of electronic devices and equipment to efficiently convert high-voltage AC (alternating current) power from the mains supply to low-voltage DC (direct current) power suitable for powering electronic circuits.

Features

1. Current mode PWM control

2. PWM and frequency modulation functions: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction

3. Built-in Slope Compensation circuit: avoids subharmonic oscillation

4. Automatic Standby Mode function (Input Power < 40 mW at no load)

5. Built-in Audible Noise Suppression function during Standby mode

6. Built-in startup circuit: reduces power consumption in standby operation, and eliminates external components

7. Bias-Assist function: improves startup operation, suppresses VCC pin voltage drop in operation, and allows use of smaller VCC capacitor

8. Built-in Leading Edge Blanking function

Description

The MC14400, MC14401 are all per channel codec-filter PCM mono-circuits. These devices perform the voice digitizing and recovery, as well as the band limiting and signal restoration necessary in PCM systems. The MC14401 is the same device, but offered in an 18-pin package.

A Codec Filter PCM Mono Circuit, often referred to as a PCM (Pulse Code Modulation) codec or PCM codec filter circuit, is an electronic circuit or component used to encode, decode, and process mono audio signals using PCM, a method for digitally representing analog audio. PCM is widely used for audio transmission, storage, and processing in various applications, including telecommunication systems, digital audio recording and playback, and more.

Features

1. 18-Pin Package

2. Selectable Peak Overlaod Voltages ( 2.5, 3.15 and 3.78 Volts )

3. Access to the “Minus” Input of the Tx Input Op Amp
