JWL4024S3V3

DC-DC converters are typically employed to transform voltage from higher to lower, or vice versa. In these applications, either the voltage or the current must be changed; the JWL4024S3V3 is a DC-DC converter that can be used for either purpose. This device utilizes synchronous rectification, which means that the energy from the input power is transferred more efficiently to the output load.

The JWL4024S3V3 is designed to convert an input voltage between 4.75V and 24V into a regulated output voltage of 3.3V. It is rated for up to 5 Amps of output current, and can operate at a switching frequency of up to 500kHz. Internal soft start functionality enables the device to start from off and transition smoothly to a stable output. It also comes with numerous protection features, such as over-temperature protection and output current limiting.

Working Principle

The JWL4024S3V3 is based on a switching regulator, which means that it uses circuit elements that can be switched rapidly on and off in order to regulate the output voltage. This is accomplished by using a pair of switches (typically implemented as transistors) to “chop” the input current into small pulses. A control system then modulates this chopping action in order to regulate the output voltage.

The input current is first converted into high-frequency AC using an oscillator, which is then filtered and rectified into DC. This DC is fed into the two transistors, which modulate it depending on the control system’s input. This modulation is adjusted based on the output voltage, meaning that it will decrease the pulse width if the voltage is too high, and increase it if it is too low. This enables the JWL4024S3V3 to maintain a regulated output voltage, regardless of changes in the input voltage or load current.

Application Field

The JWL4024S3V3 is designed for use with applications requiring a 3.3V output, such as microcontrollers, cellular phones, PDAs, and automotive systems. It can be used in a wide range of applications, including laptop and desktop computer power supplies, and is also suited for use in high efficiency systems due to its synchronous rectification technology.

The JWL4024S3V3 offers excellent efficiency and stability over a wide range of load conditions. It is well-suited to operate in harsh environments, as it is packaged in a shielded 3-pin SIP package. This makes it ideal for applications where space and cost are key considerations.

The JWL4024S3V3 is a power IC that is capable of delivering a regulated output voltage with excellent efficiency and stability. Its versatility makes it suitable for a wide range of applications, from automotive systems to laptop and desktop computer power supplies.
