The TPS563201 and TPS563208 are simple-to-use 3A synchronous buck converters in a small outline transistor (SOT)-23 package.

Both devices are optimized to minimize external components required for operation and to achieve low standby current.

These switch-mode power supply (SMPS) devices feature D-CAP2 mode control, provide fast transient response, and support low equivalent series resistance (ESR) output capacitors such as polymers and ultra-high voltage without external compensation components. Low ESR Ceramic Capacitors.

The TPS563201 can operate in pulse skipping mode to maintain high efficiency during light load operation. The TPS563201 and TPS563208 are available in a 6-lead 1.6mm × 2.9mm SOT (DDC) package and are rated for a junction temperature range of –40°C to 125°C.
