Texas Instruments Introduced a Simple 4.3-V to 17-V Input, 2-A Synchronous Buck Converter in SOT563

Texas Instruments (TI) introduced a simple, easy-to-use, 2-A synchronous buck converter TPS562207 in a SOT563 package. The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current.

This switch mode power supply (SMPS) device employs D-CAP2 mode control providing a fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.

Features

• 2-A converter integrated 145-mΩ and 86-mΩ FETs
• D-CAP2™ Mode Control with fast transient response
• Input voltage range: 4.3 V to 17 V
• Output voltage range: 0.8 V to 7 V
• Forced continuous conduction mode
• 590-kHz switching frequency
• Low shutdown current less than 3 μA
• 2% feedback voltage accuracy (25 °C)
• Support pre-bias function
• Cycle-by-cycle overcurrent limit
• Hiccup-mode overcurrent protection
• Non-latch UVP and TSD protections
• Fixed soft start: 1.0  ms

TPS562207 operates in Forced Continuous Conduction Mode (FCCM), which maintains fixed switching frequency and output voltage ripple is very small. TPS562207 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, and specified from a –40 °C to 125 °C junction temperature.
