Texas Instruments TPS6734 Fixed 12-V 120-MA Boost-Converter Supply TPS6734IDRG4

The TPS6734 is a fixed 12-V boost converter designed to deliver an output current of 120 mA from input voltages as low as 3.75 V. It operates within a wide input voltage range of 2.7 V to 11 V and features a maximum supply current of 3 mA in shutdown mode. The device is pin-for-pin compatible with the MAX734, offering advantages such as lower supply current and higher output capabilities. This boost converter utilizes a 170-kHz current-mode PWM controller and includes an n-channel MOSFET power switch, which enhances efficiency, particularly at input voltages below 5 V. The TPS6734 achieves a typical efficiency of 85% at a 5-V input and 120-mA output. It requires only five external components for operation, making it suitable for compact designs. The TPS6734 is available in both 8-pin SOIC and DIP packages and operates over a temperature range of -40¬8C to 85¬8C, making it suitable for various applications, including flash memory programming and battery-powered devices.
