TPS61130RSAR is a step-up DC-DC voltage regulator designed with a high efficiency, fast transient response and a small form factor. The device is designed to provide higher current levels and improved system efficiency, with a wide input voltage range and a selection of output voltages. It is available in two versions, with a fast (R) and slow (S) transient response. The TPS61130RSAR is ideal for applications that require a high efficiency step-up DC-DC voltage regulator with a small form factor, high current levels and fast transient response.

The TPS61130RSAR has a wide input voltage range of 4 V to 40 V and a selection of output voltages including 3.3 V, 5 V, 12 V and 18 V. The device features a high-efficiency operation with a switching frequency of up to 1.8 MHz, allowing for a smaller form factor, and also has a fast (R) and slow (S) transient response. The device also includes a current limit and soft start function, which helps protect the system from damage due to inrush current. Additionally, the TPS61130RSAR provides programmable output voltage and over-voltage protection.

The TPS61130RSAR operates in three distinct modes of operation, depending on the load conditions. In the pulse width modulation (PWM) mode, the device operates in an efficient and low ripple mode up to 500 mA with a switching frequency of 1.8 MHz. For loads between 500 mA and 1.5 A, the device operates in a pulse frequency modulation (PFM) mode, providing high efficiency without having to sacrifice a low ripple voltage. For loads exceeding 1.5 A, the device operates in a hysteretic PFM mode with a reduction in switching frequency to reduce power dissipation.

The TPS61130RSAR is applicable to a wide range of applications, including automotive, industrial, and consumer electronics, such as portable lighting, TVs, and multimedia products. Other applications include smart home appliances, computing, gaming, and others. This device is designed to provide higher current levels, improved efficiency and fast transient response, making it a suitable choice for high-load applications.

In summary, the TPS61130RSAR is a high-efficiency step-up DC-DC voltage regulator with a wide input voltage range and a selection of output voltages. The device is suitable for a wide range of applications requiring a high current, high efficiency and fast transient response, with a small form factor. The device includes a current limit and soft start function and operates in three distinct modes depending on the load conditions.
