Overview

The TPP36609Q is a high-efficiency synchronous stepdown regulator with integrated high-side and low-side MOSFETs. It provides up to 6-A output current with constant frequency, peak current mode control for fast loop response. The switching frequency is resistor programmable from 200 kHz to 2.2 MHz.

The TPP36609Q operates over a wide input voltage range from 3 V to 36 V with ultra-low quiescent current. It is ideal for automotive environments and battery-powered systems due to its extremely low quiescent current. The switching frequency automatically foldbacks to improve efficiency in the light load or standby operation. With external bias option and low integrated MOSFET resistance, the device can also ensure high efficiency in the full load range.

The TPP36609Q features 55-ns minimum on time and low drop-out mode, which can maintain stable operation for high-frequency automotive conditions. EMI performance is specially optimized in TPP36609Q. The device features a frequency spread spectrum method, adjustable switch node slew rate, optimized symmetrical pinout, and EMI friendly package to optimize the EMI emissions.

The TPP36609Q integrates soft recovery from low-dropout mode to reduce the output overshoot. The TPP36609Q has built-in robust protections such as thermal shutdown, UVLO, OVP, enable (EN) control, and power good (PG) indicator. Additionally, during the overload or short circuit condition, the accurate cycle by cycle current limit and hiccup protection are provided. Thermal shutdown provides reliable and fault-tolerant operation.

The TPP36609Q is available in the QFN4x3.5-14 package.
