3 Description
The TPS62A0x family of devices are synchronous
step-down buck DC-DC converters optimized for high
efficiency and compact solution size. The devices
integrate switches capable of delivering an output
current up to 2 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 TPS62A0xA variants of this
device family operate in forced PWM across the
whole load current range.
The TPS62A0x 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.
