Texas Instruments TPS40422RHAT 直流控制器
TEXAS INSTRUMENTS TPS40422RHAT DC/DC Controller with PMBus Interface, 4.5V to 20V, 2 Outputs, Synchronous Buck, 1MHz, VQFN-40
TEXAS INSTRUMENTS
The TPS40422RHAT is a dual-output PMBus protocol synchronous Buck Controller can be configured also for a single, two-phase output. The wide input range supports 5 and 12V intermediate buses. The accurate reference voltage satisfies the need of precision voltage to the modern ASICs and potentially reduces the output capacitance. Voltage mode control is implemented to reduce noise sensitivity and also ensures low duty ratio conversion. Using the PMBus protocol, the device margining function, reference voltage, fault limit, UVLO threshold, soft-start time, turn-on delay and turn-off delay can be programmed. In addition, an accurate measurement system is implemented to monitor the output voltages, currents and temperatures for each channel. Dual-output or two-phase synchronous buck controller PMBus interface capability Margining up/down with 2mV step Programmable fault limit and response Output voltage, output current monitoring Programmable UVLO on/off thresholds Programmable soft-start time and turn-on and turn-off delay On-chip non-volatile memory (NVM) to store custom configurations 180° Out-of-phase to reduce input ripple Inductor DCR current sensing Voltage mode control with input feed forward Current sharing for multiphase operation Supports pre-biased output Differential remote sensing External SYNC BPEXT pin boosts efficiency by supporting external bias power switch over OC/OV/UV/OT Fault protection Green product and no Sb/Br Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
