The switching frequency of 2MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs. In addition, a 470mA LDO with external voltage adjustment is provided. The LDO is capable of working at the VCC supply. The TS30021/22/23 utilizes current mode feedback in normal regulation PWM mode. When the regulator is disabled (EN is low), the device draws less than 10uA quiescent current. The TS30021/22/23 integrates a wide range of protection circuitry including input supply under- voltage lockout, output voltage soft start, current limit, and thermal shutdown. The TS30021/22/23 includes supervisory reporting through the PG (Power Good) open drain output to interface other components in the system. APPLICATIONS On-card switching regulators Set-top box, DVD, LCD, LED supply Industrial power supplies Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 2% output tolerance Adjustable version output voltage range: 0.8V to 5V with +/- 1.5% reference Wide input voltage range TS30021/22/23: 4.5V to 16V (18V Abs Max) 2MHz +/- 10% fixed switching frequency Continuous output current: 1A (TS30021), 2A (TS30022) and 3A (TS30023) 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 shutdown mode Low external component count LDO has adjustable output voltage 0.8V to 5V and 470mA output current capability SUMMARY SPECIFICATION Junction operating temperature -40 °C to 125 °C Packaged in a 16pin QFN (3x3) High Efficiency 1A/2A/3A Current-Mode Synchronous Buck DC/DC Converter, 2MHz and 470mA LDO DESCRIPTION FEATURES TYPICAL APPLICATIONS |
