The TPS40190 from Texas Instruments is a cost-optimized, fixed-frequency, voltage-mode synchronous buck controller designed for power supply applications.
This controller operates with an input voltage range of 4.5 V to 15 V and features a reference voltage of 0.591 V with ±1% accuracy. It implements an adaptive anti-cross conduction scheme to prevent shoot-through current and offers selectable short-circuit protection thresholds. The device includes an internal 5-V regulator for housekeeping and driver power, as well as internal soft-start and a bootstrap diode.
The TPS40190 utilizes strong 1.2-A drivers to minimize switching losses, allowing for the use of larger MOSFETs without significant switching time penalties. It operates at a fixed switching frequency of 300 kHz.
Packaged in a small 3 mm × 3 mm, 10-pin SON package, the TPS40190 is suitable for surface-mount applications. Its features make it applicable in devices such as cable modems, digital set-top boxes, graphics/audio cards, and entry-level to mid-range servers.
The input operating voltage range is 4.5 V to 15 V.
The fixed switching frequency is 300 kHz.
The device is offered in a 10-pin SON (VSON) package with a body size of 3 mm x 3 mm.
The operating temperature range is -40°C to 85°C.
The reference voltage is 0.591 V with ±1% tolerance.
The maximum output current is 20 A.
The drivers are rated at 1.2 A typical.
