TPS61130PWRG4 is a synchronous rectified step-down voltage converter, which is embedded with Power Stage and Voltage Regulation Loop (VRM). It belongs to the Linear + Switching Regulators of Power Management ICs (PMICs). The TPS61130PWRG4 is designed for all kinds of consumer Electronic products with low power requirements.

The TPS61130PWRG4 is widely used in consumer electronics applications, such as mobile phones, portable media players, consumer televisions, computers, and more. It can provide up to 200 mA of output current, while providing a wide input voltage range from 2.9 V to 5.5 V. The TPS61130PWRG4 is also capable of delivering a 0.5-MHz switching frequency, low quiescent current of 220 µA and adjustable output voltage range of 0.8 V to 1.8 V.

The TPS61130PWRG4\'s power stage adopts the synchronous rectified step-down technique. The synchronous rectified step-down technique includes two power MOSFETs, one high-side and one low-side corresponding respectively to the NMOS and PMOS, these two MOSFETs have a high switching efficiency, reducing the power loss, also low noise and EMI. So, it helps for customers to reach their goals about efficiency, as well as reduce size and cost.

The TPS61130PWRG4 also contains current-mode control and voltage regulation loop with fast transient response capability, which can provide good line and load regulations under fast transient and changeable load conditions. It also features overload protection, current foldback, short-circuit protection (SCP) and thermal limiting protection. Those protection function also make it suitable for both mobile and standalone devices.

The TPS61130PWRG4 also includes an enable pin to put the device into either normal mode or shutdown mode, in order to save power consumption and increase the system performance. The enable pin has an internal pull-down to keep the device in shutdown mode. The enable pin can be pulled high with a 6.2K resistor or any other higher ohm resistor.

To sum up, the TPS61130PWRG4 is an optimal solution for all kinds of consumer electronics applications with low power consumption. It has low input voltage, wide output voltage range, low power loss, short circuit protection and can be enable/disable externally, make it a perfect solution for users.
