DC DC Converters

The DC DC converters are electrical devices that convert electrical energy from one form or voltage level to another form or voltage level either through a switch or directly. DC DC converters can be classified into two categories based on the type of output they produce: switch-mode converters (who convert an input voltage into a variable output voltage and a fixed output voltage) and linear converters (who produce an output voltage that is proportional to the input voltage). One of the common types of DC DC converter is the LTM8008HV#PBF Family of DC DC Converter.

LTM8008HV#PBF Applications

The LTM8008HV#PBF DC DC converter is a high-performance DC DC converter that is designed to provide power conversion solutions for a variety of industrial, automotive, and consumer markets. It offers efficient power conversion with wide input ranges that can adjust from 0.8 V to 18 V, and an output range of ±1.5 V to ±15 V. It also features a programmability that allows the user to select an operating frequency between 300 kHz to 1 MHz, as well as ramp compensation to optimize situations with high inrush current power requirements. The LTM8008HV#PBF DC DC converter is also equipped with a high-efficiency drive circuit with a high-side MOSFET that is capable of delivering up to 30 A of continuous current. It also offers a wide range of control, protection, monitoring, and diagnostic features, including a soft start, hiccup mode, over current protection, under voltage lockout, and an overtemperature shutdown.

Working Principle and Design Features

The LTM8008HV#PBF DC DC converters incorporate a key feature adapted from switch-mode power supplies (SMPS) called a synchronous rectification and regulated rectification design. This feature combines the advantages of both regulator and synchronous rectifier, allowing multiple power supply output levels to be precisely regulated without having to resort to a linear regulator. This design utilizes an integrated circuit with a programmable logic block for controlling the conversion switch sequences. It operates by applying pulses of current through the power switch, allowing power to be efficiently converted from an input to an output voltage. This is referred to as a ‘pulsed’ switching operation. During the pulse, the inductor or capacitor is charged at a rate depending on the time-variable currents. When the current goes off, the inductor or capacitor is discharged through an opposite switch or diode to the output.

The LTM8008HV#PBF family of DC DC converters is an excellent choice for applications requiring a high-performance, efficient, and reliable DC DC converter. Its wide range of features provide optimal performance in a variety of applications, and its design ensures a safe and secure operation. The LTM8008HV#PBF provides an immediate solution for power regulated applications requiring a wide input voltage span with high-efficiency and high-performance.
