The TPS78633KTTT is a robust controller IC optimally designed for premium notebook and tablet applications. It is a triple-output core voltage regulator that operates with input voltages between 2.6 and 6.0 V. It includes three linear regulator buck converters. Two outputs are derived from a single inductor topology and the third output is derived from the buck configured input supply. The device also includes an integrated power-on reset, low voltage monitor and an overcurrent protection.

The dual output core buck regulator has an adjustable output voltage range from 0.6 V to 1.2 V in nearly 0.1 V increments. A single-ended sense voltage is used that can be located remotely from the buck converter and ranges from 0.3 V to 2.6 V. The input supply is protected by a 0.6 V foldback in case of a fault condition. It has an integrated EMI filter which reduces high frequency noise on the output.

The other buck regulator has an adjustable output voltage range from 0.5V to 2.4 V in nearly 0.1 V increments. The output voltage is adjusted via an I2C output control interface. This buck regulator features a fast transient response with a 150 μs minimum step response time. It also has an integrated low quiescent current control logic that reduces the input supply leakage current.

The TPS78633KTTT also features an adjustable overcurrent protection and SKU Voltage Sense terminals to select output voltage levels. It is available in a green 24-lead WLCSP package and operates over a temperature range of –40 °C to +105 °C.

In essence, the TPS78633KTTT is an advanced voltage regulator of the linear type, effectively meeting the stringent requirements of modern notebook and tablet applications. It includes three linear regulator buck converters with adjustable output voltages, adjustable overcurrent protection, integrated power-on reset and low voltage monitor, integrated EMI filter and I2C output control interface.

In addition, the TPS78633KTTT has a quiescent current control logic that reduces input supply leakage current, while its fast transient response time ensures that the output voltage remains stable even in dynamic conditions. Finally, its compact WLCSP package and wide operating temperature range make it suitable for a variety of challenging applications.
