LTC7103HUHE#TRPBF is a low-noise, high-efficiency synchronous-rectified step-down converter from Linear Technology Corporation. It provides up to 1.5A output over an input voltage range from 1.5 to 24V. The converter has a low dropout voltage and wide operating frequency range, up to 2.2MHz. It employs a power dissipative switch and a voltage-mode control architecture for high output voltage accuracy and reliability. The integrated MOSFETs provide optimized, low-dropout operation and high efficiency. The device has a separately floating output. Included features are cycle-by-cycle current limit, as well as adjustable under-voltage lock-out, output short-circuit protection and thermal shut-down. An adjustable soft-start and adjustable output voltage setpoint help to prevent large inrush current and wiring problems.

The LTC7103HUHE#TRPBF belongs to the PMIC (Power Management ICs) Voltage Regulators DC-DC Switching Regulators category. This device is a DC-DC converter that uses a complex power stage combining a power dissipative switch with a voltage-mode control architecture to provide high output voltage accuracy, low dropout voltage, high efficiency, and wide operating frequency range. It can regulate an output voltage from its input voltage (commonly an unregulated voltage or another regulated voltage) without the need for an external transformer or a power stage. This feature gives it the advantage of high energy density and reduced size.

The working principle of LTC7103HUHE#TRPBF is based on a synchronous-rectified step-down converter. It is made of efficient power stages with MOSFET switches, a current-sensing control block and a voltage-sensing control block. The voltage-sensing block constantly measures the output voltage. For input voltage higher than output voltage, the MOSFETs are on and deliver current to the inductor. When the input voltage is lower than the output voltage, the MOSFETs are off and the current stored in the inductor is delivered to the output through the body diode. The voltage-sensing block compares the output voltage and the reference voltage. If the output voltage is higher than the reference voltage, the voltage-sensing block signals the voltage comparator to decrease the duty cycle, thus reducing the current delivery to the output.

The main advantages of the LTC7103HUHE#TRPBF are its wide operating frequency range, low dropout voltage, high output voltage accuracy, and its low noise. The high output voltage accuracy enables precision applications, such as portable medical or general-purpose equipment. The device also includes protection features include cycle-by-cycle current limit, under-voltage lockout, output short-circuit protection and thermal shut-down, which provide a safe and secure operation. In addition, the adjustable soft-start and adjustable output voltage setpoint prevent large inrush current and wiring problems.

The LTC7103HUHE#TRPBF is suitable for use in a wide range of applications, including input and output power supplies, distributed power systems, portable consumer products, wireless LANs, cellular telephones, digital cameras and other consumer electronics. The device is also suitable for automotive and industrial applications requiring advanced power-management features, high efficiency and low noise.
