评估模块, 用于直流至直流转换器, 提供高达2.5A输出
The is an evaluation module for TPS54260 dc/dc converter, designed to provide up to a 2.5A output from an input voltage source of 3.5V to 60V. This evaluation module is designed to demonstrate the small, printed circuit board areas that may be achieved when designing with the TPS54260 regulator. The switching frequency is internally set at a nominal 500kHz. The high side MOSFET is incorporated inside the TPS54260 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS54260 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit IC and an external divider allows for an adjustable output voltage. Additionally, the TPS54260 provides adjustable slow start and under voltage lockout inputs. The absolute maximum input voltage is 60V for the TPS54260EVM-597.
