TS30012

TS30011/12/13 High Efficiency 1A/2A/3A Current-Mode Synchronous Buck DC/DC Converter, 1MHz TRIUNE PRODUCTS Features Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 2% output tolerance Adjustable version output voltage range: 0.9V to (VCC – 1V) with +/-1.5% reference. Wide input voltage range ŒŒ TS30011/12: 4.5V to 24V (26.4V Abs Max ŒŒ TS30013: 4.5V to 18V (20V Abs Max) 1MHz +/- 10% fixed switching frequency Continuous output current: 1A (TS30011), 2A (TS30012) and 3A (TS30013) High efficiency – up to 95% 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 Applications On-card switching regulators Set-top box, DVD, LCD, LED supply Industrial power supplies Description The TS30011 (1A), TS30012 (2A) and TS30013 (3A) are 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 TS30011/12/13 utilizes current mode feedback in normal regulation PWM mode. When the regulator is placed in standby (EN is low), the device dra...
