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
● High output voltage (up to 38V)
● 1.2A Integrated switch
● 12V at 300mA and 24V at 150mA from 5V input (typical)
● Up to 93% efficiency
● Output voltage reprogramming
● Skip-switching cycle for output regulation at light load
● Built-in soft start
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
