TPS54J061RPGR

The TPS54J061 device is a high-efficiency, small-size synchronous buck converter featuring adaptive on-time D-CAP3™ control mode. This device is easy to use, requires minimal external components, and is well-suited for space-constrained power systems. It features high-performance integrated MOSFETs, a ±1% accurate 600mV reference voltage, and a junction temperature range of -40°C to +125°C, along with the following competitive characteristics: ultra-low external component count, fast load transient response, accurate load and line regulation, operation in auto-skip or FCCM mode, adjustable soft-start control, and support for all-ceramic capacitor designs without external compensation. The TPS54J061 is available in a 14-pin QFN package. The TPS54J061 device is a high-efficiency, single-channel, small-size synchronous buck converter. It is designed for point-of-load applications with output currents up to 6A at low output voltages in servers, storage, and similar computing applications. The TPS54J061 features proprietary D-CAP3™ control mode with an adaptive on-time architecture. This combination is ideally suited for modern DC/DC converters requiring low duty cycles and ultra-fast load step response. The output voltage range is 0.6V to 5.5V. The conversion input voltage range is 2.7V to 16V, and the VCC input voltage range is 3V to 3.6V. D-CAP3 control mode uses analog current information to control modulation. One advantage of this control scheme is that it requires no external phase compensation network, making the device easy to use with a minimal external component count. Another advantage is that it supports stable operation with an all-ceramic output capacitor design. The adaptive on-time control feature tracks a preset switching frequency across a wide input and output voltage range, while increasing the switching frequency as needed during load step transients.
