Part#: TPS62113RSAT

Part Category: Other Semiconductors

Manufacturer: Texas Instruments High-Performance Analog

Description: Switching Regulator, Voltage-mode, 1.5A,…

The TPS6211x devices are a family of low-noise • High-Efficiency Synchronous Step-Down
synchronous step-down DC-DC converters that are Converter With up to 95% Efficiency ideally suited for systems powered from a 2- to 4-cell
• 3.1-V to 17-V Operating Input Voltage Range Li-ion battery or from a 12-V or 15-V rail.
• Adjustable Output Voltage Range: 1.2 V to 16 V
The TPS6211x devices are synchronous pulse width
• Fixed Output Voltage Options Available in modulation (PWM) converters with integrated N- and
3.3 V and 5 V P-channel power MOSFET switches. Synchronous
• Synchronizable to External Clock: Up to 1.4 MHz rectification is used to increase efficiency and to
reduce external component count. To achieve highest • Up to 1.5-A Output Current efficiency over a wide load-current range, the
• High Efficiency Over a Wide Load-Current converter enters a power-saving, pulse frequency
Range Due to PFM/PWM Operation Mode modulation (PFM) mode at light load currents.
• 100% Maximum Duty Cycle for Lowest Dropout Operating frequency is typically 1 MHz, allowing the
use of small inductor and capacitor values. The • 20-µA Quiescent Current (Typical)
device can be synchronized to an external clock
• Overtemperature and Overcurrent Protected signal in the range of 0.8 MHz to 1.4 MHz. For low-
• Available in 16-Pin VQFN Package noise operation, the converter can be operated in
PWM-only mode. In shutdown mode, the current
2 Applications consumption is reduced to less than 2 µA. The
TPS6211x family of devices are available in the 16-
• Point-of-Load Regulation From 12-V Buses pin (RSA) VQFN package, and operate over a free-
• Organizers, PDAs, and Handheld PCs air temperature range of –40°C to 85°C.
