TPS61378-Q1 pdf资料下载The TPS61378-Q1 is a fully-integrated synchronous boost converter with load disconnect function integrated. The device is suitable as a post-boost for automotive applications with a programmable current limit up to 4.8-A and maximum 18.5 V output voltage. It supports an input voltage from 2.3 V to 14 V and 25-μA low quiescent current. The TPS61378-Q1 employs the peak current-mode control with the switching frequency programmable from 200 kHz to 2.2 MHz. In medium to heavy load, the TPS61378-Q1 works in fixed frequency PWM operation with the frequency set by an external resistor. In light load, the TPS61378-Q1 offers two optional modes: Auto PFM or Forced PWM which is configured by the mode pin externally. In Auto PFM mode, the switching frequency is lowered at light load to improve the efficiency. In Forced PWM mode, the switching frequency is kept constant across the entire load range. The switching frequency can be synchronized to an external clock. PTPS61378QWRTERQ1 TPS61378QWRTERQ1 TPS61378QWRTETQ1 Datasheet pdf资料数据表下载
