The TPS62A01x-Q1 family of devices are synchronous step-down buck DC-DC converters optimized for high efficiency and compact design size. The devices integrate switches capable of delivering an output current up to 1 A. At medium to heavy loads, the devices operate in pulse width modulation (PWM) mode with 2.4-MHz switching frequency. At light load, the devices automatically enter power save mode (PSM) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is minimal as well. The TPS62A01A-Q1 variants of this device family operate in forced PWM across the whole load current range.

The TPS62A01x-Q1 devices provide an adjustable output voltage through an external resistor divider. An internal soft-start circuit limits the inrush current during start-up. Other features like overcurrent protection, thermal shutdown protection, and power good are built-in. The devices are available in a SOT-563 package.
