The TPS40222 is a fixed-frequency, current-mode, non-synchronous buck converter optimized for applications powered by a 5-V distributed source. With internally determined operating frequency, soft-start time, and control loop compensation, the TPS40222 provides many features with a minimum of external components.
The TPS40222 operates at 1.25 MHz and supports up to 1.6-A output loads. The output voltage can be programmed to as low as 0.8 V. The TPS40222 utilizes pulse-by-pulse current limit as well as frequency foldback to protect the converter during a catastrophic short circuited output condition.
