The TPS62A02-Q1 and TPS62A02A-Q1 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 2A. At medium to heavy loads, the devices operate in pulse width modulation (PWM) mode with 2.2MHz switching frequency. At light load, the TPS62A02-Q1 automatically enters a power save mode (PSM) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is minimal as well. The TPS62A02A-Q1 variant of this device operates in forced PWM across the whole load current range and maintains a constant switching frequency.

The TPS62A02x-Q1 devices provide an adjustable output voltage through an external resistor divider. An internal soft-start circuit limits the inrush current during start-up and a power good signal indicates when the output voltage is at target. Overcurrent protection and thermal shutdown protect application and device. The devices are available in an SOT-563 package.
