The device is ideally suited as a pre- V), Operation Down to 2 V When Boost Is regulator stage with low IQ requirements and for Enabled systems that must survive supply drops due to • Low-Power Mode IQ: 34 µA (One Buck On), 43 cranking events. The integrated boost controller µA (Two Bucks On) allows the device to operate down to 2 V at the input without seeing a drop on the buck regulator output • Low Shutdown Current Ish < 4 µA stages. At light loads, the buck controllers enable to • Boost Output Selectable: 7 V, 8.85 V, or 10 V operate automatically in low power-mode, consuming • Programmable Frequency and External just 34 µA of quiescent current. Synchronization Range: 150 to 600 kHz The buck controllers have independent soft-start • Separate Enable Inputs (ENA, ENB, ENC) capability and power-good indicators. Current foldback in the buck controllers and cycle-by-cycle • Selectable Forced Continuous Mode or current limitation in the boost controller provide Automatic Low-Power Mode at Light Loads external MOSFET protection. The switching • Sense Resistor or Inductor DCR Sensing for frequency is programable over 150 to 600 kHz or is Buck Controllers synchronized to an external clock in the same range • Out-of-Phase Switching Between Buck Channels Figure 1.
