LINEAR TECHNOLOGY LT8709EFE#PBF 控制器, PWM, -4.5V-80V电源, 750 kHz, TSSOP-20
The is a synchronous PWM Controller for negative-to-negative or negative-to-positive DC/DC conversion with rail-to-rail output current monitor and control. It is ideal for many local power supply designs. It can be easily configured in buck, boost, buck-boost and inverting topologies with negative input voltages. In addition, the LT8709"s rail-to-rail output current sense allows the part to be configured in current limited applications such as battery or capacitor charging. The PG pin is used for power good indication. The LT8709"s switching frequency range can be set between 100 and 750kHz. The part may be clocked internally at a frequency set by the resistor from the RT pin to the -VIN pin, or it may be synchronized to an external clock. The LT8709 also features innovative EN/FBIN pin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function.
