DC-DC converters are a versatile tool for powering any device that requires a steady amount of current, from motors to electronic circuits. The TDR 3-4823WISM is an efficient, low-cost, single-chip DC-DC converter that is well suited to a broad range of applications. The converters provide input voltage capability of 4.5V to 28V DC, with a peak output current of 1.2A.

The TDR 3-4823WISM utilizes a fixed-frequency pulse-width modulation (PWM) control technique and employs an integrated series buck regulator. This allows for efficient conversion of input voltages to a steady output voltage, and provides high accuracy without the need for an external voltage reference. The PWM control technique is highly stable in operation and allows for frequency adjustment through a range of 0.1 Hz to 1 kHz.

The series buck regulator of the TDR 3-4823WISM generates high efficiency operation with low start-up current (27mA) and very low quiescent current (2mA). Furthermore, it has a very low ripple and noise level, making it suitable for powering sensitive loads. The converter can also be used for step up, step down and other power conditioning applications.

In addition to the control circuitry, the TDR 3-4823WISM includes an internal temperature compensated over-voltage, under-voltage and over-current protection circuit. This additional safety feature is useful for controlling the operating limits of the converter and protecting it against any short circuit conditions. The output enable / disable feature of the converter also allows easy shutdown of the converter during idle periods.

The TDR 3-4823WISM DC-DC converter is an optimally designed, cost-effective option for a wide variety of low power electronics applications. Its high efficiency, low current start-up, low ripple and noise levels, over-voltage, under-voltage and over-current protection circuits, and output enable/disable feature, make it an ideal choice for powering sensitive electronic circuits. Its adjustable switching frequency and compact size make it a great choice for applications where space and cost are a factor.
