Регуляторы напряжения - Импульсные регуляторы TPS61170DRVT

Импульсный повышающий DC-DC стабилизатор , регулируемый, 3В-18В (Vin), 3В-38В, 1.2А, SON-6

The TPS61170DRVT is a High Voltage Boost Converter that can be configured in several standard switching-regulator topologies, including boost and SEPIC. The device has a wide input-voltage range to support applications with input voltage from multicell batteries or regulated 5, 12V power rails. It operates at a 1.2MHz switching frequency, allowing the use of low-profile inductors and low-value ceramic input and output capacitors. External loop compensation components give the user flexibility to optimize loop compensation and transient response. The device has built-in protection features, pulse-by-pulse over-current limit, soft start and thermal shutdown. The FB pin regulates to a reference voltage of 1.229V. The reference voltage can be lowered using a 1-wire digital interface (EasyScale™ protocol) through the CTRL pin. Alternatively, a pulse width-modulation signal can be applied to the CTRL pin. The duty cycle of the signal reduces the feedback reference voltage proportionall
