DC DC Converters: PT6724A Application Field and Working Principle

The PT6724A is a high-performance DC to DC converter that offers a wide range of output voltages at ultra-high efficiency. It is designed for applications where space and energy efficiency are key performance objectives. It is a suitable choice for telecom, military, aerospace, and industrial applications where low-noise, high-efficiency, and reliable DC-DC conversion is critical.The PT6724A is a non-isolated synchronous buck DC-DC converter that is capable of providing up to 19W of output power over a wide input voltage range of 2.4V to 12V with guaranteed minimum efficiency of 95%. It uses a fixed frequency PWM (pulse-width modulation) control scheme, and has a switching frequency of up to 1.2 MHz. The converter features built-in Over-Temperature Protection (OTP), Over-Voltage Protection (OVP), Current Limit Protection (CLP), and Short-Circuit Protection (SCP) to ensure reliable operation and protect against unexpected environmental conditions.The PT6724A DC-DC converter operates by converting a DC input voltage into a DC output voltage at a higher or lower voltage. The device features a synchronous buck converter topology, which means that both the input and the output energy are connected to the same switching node. The input voltage is applied to a power transistor (or ‘switch’) that is repeatedly switched on and off at a predetermined frequency. The timing of the switch is controlled by an external control signal. When the switch is on, energy is transferred from the input to the output. When it is off, the output voltage is kept constant by an inductor and capacitor network, which is also used to provide the output current.The PT6724A features many advanced features that make it an ideal choice for high-performance and high-efficiency applications. It features an integrated dual-input power transistor, a low input quiescent current, a low input current ripple, a wide input voltage range, a high output voltage accuracy, and a quick transient response. Additionally, the PT6724A offers programmable frequency and PWM dimming control, and a low total harmonic distortion (THD).In summary, the PT6724A is an efficient high-performance DC-DC converter that is perfect for a wide variety of applications. It offers a wide input voltage range, a high output voltage accuracy, a wide range of output voltages at ultra-high efficiency, a low quiescent current, an integrated dual-input power transistor, a quick transient response, and programmable frequency and PWM dimming control. Combined with its built-in protections, the PT6724A is an excellent choice for telecom, military, aerospace, and industrial applications where reliable and energy-efficient DC-DC conversion is required.
