The TPS562201 and TPS562208 are simple-to-use 2A synchronous buck converters in a SOT-23 package.

The device is optimized to operate with as few external components as possible and to achieve low standby current.

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

The TPS562201 can operate in pulse skipping mode to maintain high efficiency during light load operation. The TPS562201 and TPS562208 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.
