TPS53126 

Dual synchronization Buck controller for low-voltage power rails at 350kHz or 700kHz

illustrate   The TPS53126 is a dual-channel, adaptive turn-on time with a CAP2 mode synchronous buck controller. This TPS53126 enables system designers to complete a regulated power bus kit for a variety of end devices with a cost-effective, low external component count, and low standby current solution. D-CAP2 mode control for TPS53126 main control cycle provides a very fast transient response without the need for external components. The TPS53126 also features dedicated circuitry that allows the device to accommodate output capacitors with two low equivalent series resistors (ESRs), such as POSCAP or SP-CAP ceramic capacitors with ultra-low ESR. The device offers input voltages from 4.5 V to 24 V, while output voltages from 0 for convenient and efficient operation.   characteristic   ð - CAP2™ mode control Fast transient response For parts that require no external loop compensation Suitable for ceramic output capacitors High initial reference accuracy (± 1%) Low output ripple Wide input voltage range: 4.5 V to 24 V Output voltage range: 0.76 V to 5.5 V The low-end R DS (top) has no lossless current sensing Adaptive gate driver with integrated boost diode Internal 1.2 ms voltage soft-start servo Pre-biased soft start Selectable switching frequency: 350 kHz / 700 kHz Cycle-by-cycle overcurrent limit control OCP threshold voltages from 30 mV to 300 mV The heat compensation trip of OCP is reduced to 4000 ppm/1 °C, apply Point load regulation is widely used in low-power systems Digital TV power supply Network home terminal
