TEXAS INSTRUMENTS TPS65261RHBT 直流-直流开关降压, 逐步递降稳压器, 可调, 4.5V-18V输入, 600mV3A输出, 2MHz, VQFN-32
The is a monolithic triple synchronous Step-down/Buck Converter for use with set-top boxes. A wide 4.5 to 18V input supply voltage range encompasses the most intermediate bus voltages operating off 5, 9, 12 or 15V power bus. The converter, with constant frequency peak current mode, is designed to simplify its application while giving designers options to optimize the system according to targeted applications. The switching frequency of the converters can be adjusted from 250kHz to 2MHz with an external resistor. The 180° out-of-phase operation between Buck1 and Buck2, 3 Buck2 and 3 run in phase minimizes the input filter requirements. It features an automatic power sequence with connecting MODE pin to V7V and configuring EN1/2/3 pins. The device also features an open-drain RESET signal to monitor power down. At light load, the TPS65261 automatically operates in pulse skipping mode PSM. PSM mode provides high efficiency by reducing switching losses at light loads.
