概述

The TPP36307Q is a high-efficiency synchronous stepdown regulator with integrated high-side and low-side MOSFETs. It provides up to 3-A output current with peak current mode control for fast loop response.

The TPP36307Q operates over a wide input voltage range from 3 V to 36 V with only 6-µA ultra-low quiescent current. It is ideal for automotive environments and batterypowered systems due to its extremely low quiescent current.

The TPP36307Q features 35-ns ultra-low minimum on time and low drop-out mode, which can maintain stable operation for high-frequency automotive conditions. EMI performance is specially optimized in the TPP36307Q. The device features a frequency spread spectrum method, optimized symmetrical pinout, and EMI-friendly package to optimize the EMI emissions.

The TPP36307Q has built-in robust protections such as thermal shutdown, UVLO, enable (EN) control, and power good (PG) indicator. Additionally, during the overload or short circuit condition, the cycle-by-cycle current limit and hiccup protections are provided. Thermal shutdown provides reliable and fault-tolerant operation.

The TPP36307Q is available in the QFN2x3-12 package.
