Overview
The TPP05301 is an easy-to-use, high-efficiency, synchronous, step-down regulator with integrated highside and low-side MOSFETs. It provides up to 3-A output current and operates over a wide input voltage range.
The TPP05301 operates over a wide input voltage range from 2.5 V to 5.5 V with 25-µA ultra-low quiescent current. It is ideal for battery power systems due to its low quiescent current. The TPP05301 employs an adaptive- off time with a peak current control for fast loop response, simple loop design, and external components. The TPP05301 series supports power-saved mode to improve efficiency in light load operation and forced-PWM mode to maintain a fixed switching frequency and release low output ripple during all load conditions.
The TPP05301 has built-in robust protections such as thermal shutdown, UVLO, and enable (EN) control. Additionally, during the overload or short circuit condition, the cycle-by-cycle current limit and hiccup protection are provided. Thermal shutdown provides reliable and faulttolerant operation. A power good signal indicates that the output voltage is in correct regulation.
The TPP05301 is available in the SOT563 (1.6 mm*1.6 mm) package.
