The TPS61055DRCR is a high-power, fixed-frequency, synchronous boost converter with an integrated 2-A switch. Manufactured by Texas Instruments, this device is designed to efficiently manage power within a compact footprint, making it ideal for portable electronics where space and power efficiency are at a premium.

Operating with a switch frequency of 1.2 MHz, the TPS61055DRCR allows for the use of small surface-mount inductors and capacitors, which reduces the overall solution size and provides a quick response to load transients. It is capable of generating output voltages up to 5.5V from a battery voltage as low as 1.8V, ensuring reliable operation even as the battery voltage declines.

The device features a wide input voltage range of 1.8V to 6V, making it versatile for various applications, including but not limited to, handheld devices, battery-powered equipment, and white LED drivers. Its high efficiency is maintained over a wide load range, thanks to its synchronous rectification and low quiescent current.

The TPS61055DRCR also incorporates a range of protective features to safeguard the device and the application it powers. These include over-temperature protection, over-voltage protection, and under-voltage lockout, which ensure the device operates within safe parameters. Additionally, Texas Instruments has included a true load disconnect feature that isolates the load from the power source when the device is disabled, further enhancing battery life.

Supplied in a small 10-pin VSON package, the TPS61055DRCR is engineered for a straightforward design-in process. Its compact size, combined with a minimal external component count, makes it a highly attractive solution for designers looking to maximize power density and efficiency in their next-generation portable devices.
