The JHM0324S05 DC DC converter is increasingly being used in a variety of applications today. This article will discuss its application field and working principle.

The JHM0324S05 DC DC converter is a type of DC-DC converter that combines a two-stage regulation topology with synchronous rectification. It is based on a synchronous buck topology and uses two stages to regulate the output voltage. The topology combines a non-synchronous PFM controller and two series synchronous buck converters with independent control signals. This combination makes it possible to achieve a very wide input voltage range, a wide range of output voltages, and low cost.

This DC DC Converter can be used in a variety of applications, ranging from small and simple applications like hand-held electronic devices, to more sophisticated applications, like smartphone charger boards. For mobile applications, the JHM0324S05 has a wide input voltage range of 4.5-24 V and a maximum output current of up to 5A. It also supports low standby power by disabling the enable signal.

The working principle of the JHM0324S05 DC DC converter can be broken down into two stages. In the first stage, the PFM controller receives the input voltage and converts it into a sawtooth waveform. This sawtooth waveform is used to control the switching of two series buck converters, which then in turn, convert the input voltage into an intermediate voltage.

In the second stage, the two series synchronous buck converters, also referred to as synchronous rectification, use the intermediate voltage to regulate the output voltage. This is done by varying the duty cycle of the switching transistor, which determines the amount of current that passes through the output load circuit. By varying the duty cycle, the output voltage is regulated.

The JHM0324S05 DC DC converter is a great choice for a wide range of applications. It provides a wide input voltage range, a wide range of output voltages, and low cost. Also, it has a low standby power feature when enabled. Its two-stage regulation topology with synchronous rectification allows it to offer excellent performance for both small and large output currents.
