The TPS61170 is a monolithic high-voltage switch with an integrated 1.2A, 40 V power MOSFET regulator. It can be configured in several standard switching regulator topologies, including boost and SEPIC. The device has a wide input voltage range to support 5 V, 12 V rail voltage applications with input multi-cell or regulated supplies.

The TPS61170 operates at a switching frequency of 1.2 MHz, allowing the use of small inductors and low value-added ceramic input and output capacitors. External loop compensation components are given to optimize loop compensation and transient response user flexibility. The device has built-in protection features such as pulse overcurrent limiting, soft start, and thermal shutdown.
