TPS60255 www.ti.com SLVS825–MARCH 2008 HIGH EFFICIENCY CHARGE PUMP FOR 7 WLEDs DRIVER WITH 1 WIRE INTERFACE 1 FEATURES 2• 2.7 V to 6.0 V Input Voltage Range DESCRIPTION • 1× and 1.5× Charge Pump The TPS60255 is a high-efficiency, constant • Auto Switching Between 1× and 1.5× Modes frequency charge pump DC/DC converter that uses • 750 kHz Charge Pump Frequency 1× and 1.5× conversion to maximize efficiency for the input voltage range. By using adaptive 1×/1.5× • Seven Individually-regulated WLED charge-pump modes and very low dropout current Current Sinks regulators, the TPS60255 achieves high efficiency for • Single- Wire Interface for Dimming and the entire one-cell lithium battery range. The ON/OFF Control protection features include soft start, over-current • 25 mA max LED Current for Six Current Sinks limit, thermal shut down, and over-voltage detection. The device automatically detects and removes • One 80 mA Current Sink unused current sinks from the control loop. • Open WLED Detection This device drives six 25 mA current sinks and one • Built-in Soft Start and Current Limit 80 mA current sink. These current regulators are • 16-pin, 3 mm × 3 mm QFN Package programmed by three independent brightness registers and five ON/OFF bits using a single-wire APPLICATIONS interface (EasyScale™). This offers flexible • Cellular Phones applications for a variety of lighting control in portable devices. • Portable Navigation Displays • Multi-display Handheld Devices AUX 100 V = Sweep Down IN 4 LEDs: GA1, GA2, GA3, and GA4 Back Light 90 * LED: NSSW100CT (NICHIA) for GND GC GA4 GA3 LCD Display C1- GA2 80 GA1 C2+ 70 C2 C3 1 mF 1 mF GB2 C2- 60 ILED = 15.3 mA C1+ GB1 VIN ENA IF 50 ILED = 25.2 mA ILED = 2.1 mA VOUT 40 C4 C1 2.9 3.4 3.9 4.4 4.9 2.2 mF 4.7 mF V − Input Voltage − V IN G001 Enable/ Interface Using Disable EasyScale Figure 2.
