Descripción general

Description

The TPS6735ID is a step-up (boost) DC/DC converter from Texas Instruments, designed for applications requiring efficient voltage conversion from a lower input voltage to a higher output voltage. It typically operates with input voltages ranging from 1.8V to 5.5V and can boost this to an output of up to 12V. The device is optimized for battery-powered devices, offering high efficiency, low quiescent current, and low shutdown current. The TPS6735ID incorporates an internal switch and can deliver output currents suitable for small to medium-sized loads.
Key features of the TPS6735ID include its fixed-frequency operation which improves efficiency and minimizes electromagnetic interference (EMI). It also features internal frequency compensation and a soft-start function to limit inrush current. The package size is compact, making it suitable for space-constrained applications such as portable electronics, LCD displays, and other handheld devices.
In summary, the TPS6735ID is a reliable and efficient solution for applications needing a compact, low-cost, step-up voltage regulator. Its flexibility and performance make it a popular choice for designers working with portable and battery-operated gadgets.

Features

The TPS6735ID is a step-up DC-DC converter designed for applications requiring efficient voltage boosting. Key features include a wide input voltage range from 1.8V to 5.5V, making it suitable for battery-powered devices. It delivers a fixed output voltage, typically 5V, with an output current capability up to 500mA. The device utilizes pulse frequency modulation (PFM) for high efficiency across varying loads, maintaining efficiency levels over 90% for many applications.
The TPS6735ID features internal frequency compensation and soft-start capabilities, reducing inrush current during startup. It integrates a 1.25MHz oscillator, allowing the use of small inductors and capacitors to minimize board space. Additionally, the converter includes protection features such as overcurrent protection and thermal shutdown to ensure reliable operation.
Its compact 8-pin SOIC package and low external component count make it ideal for compact designs. The TPS6735ID is commonly used in applications like portable electronics, battery-operated devices, and any system requiring a stable boosted output voltage from lower input voltages.

Package

The TPS6735ID is a voltage inverter with a DIP (Dual In-line Package) type. It’s a standard package used for electronic components, ensuring ease of handling and installation in circuit boards typically for prototyping and low-volume production applications.

Pinout

The TPS6735ID is a step-up DC-DC converter from Texas Instruments designed to generate a higher output voltage from a lower input voltage. It is typically used in battery-powered applications where efficiency is crucial. The TPS6735ID comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Below is a brief overview of its pin functions:
1. Pin 1 (COMP): Compensation for the error amplifier. Connects to an external network to stabilize the control loop.
2. Pin 2 (FB): Feedback pin. Connects to the output voltage via a resistor divider to regulate the output voltage.
3. Pin 3 (SHDN): Shutdown control input. A high level enables the device, while a low level puts it in shutdown mode.
4. Pin 4 (GND): Ground reference for the device.
5. Pin 5 (SW): Switching node. Connects to the inductor and the diode for the step-up conversion.
6. Pin 6 (VIN): Input supply voltage.
7. Pin 7 (VOUT): Output voltage pin.
8. Pin 8 (NC): No connection or not used in the standard configuration.
The TPS6735ID is known for its efficiency, low quiescent current, and ability to provide a regulated output voltage, making it ideal for various portable and battery-operated devices.
