TPS61170QDRVRQ1

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

The TPS61170QDRVRQ1 is a monolithic high-voltage Switching Regulator with integrated 1.2A/40V power MOSFET. The device 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. The TPS61170-Q1 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, such as pulse-by-pulse overcurrent 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 (PWM) signal can be applied to the CTR
