TS30111

TS30111 High Efficiency 700mA Current-Mode Synchronous Buck DC/DC Regulator, 1MHz TRIUNE PRODUCTS Features Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V Adjustable version output voltage range: 0.8V to 5V Wide input voltage range 4.5V to 16V (18V Abs Max) 1MHz +/- 10% fixed switching frequency Continuous output current: 700mA High efficiency – up to 90% Current mode PWM control with PFM mode for improved light load efficiency Voltage supervisor for VOUT reported at the PG pin Input supply under voltage lockout Soft start for controlled startup with no overshoot Full protection for over-current, over-temperature, and VOUT over-voltage Less than 10uA in standby mode Low external component count Summary Specification Junction operating temperature -40 °C to 125 °C Packaged in a 16pin QFN (3x3) Description The TS30111 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs. The TS30111 utilizes current mode feedback in normal regulation PWM mode. When the regulator is placed in standby (EN is low), the device draws less than 10uA quiescent current. The TS30111 integrates a wide range of protection circuitry including input supply under-voltage lockout, output voltage soft start, current limit, and thermal shutdown. The T...
