SSP8099
The SSP8099 is a synchronous step-up converter . It is designed for products powered by alkaline battery, NiMH rechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation.
The SSP8099 can support up to 300mA output current from 3.3V to 5V conversion, and achieve up to 90% efficiency at 200mA load.
The SSP8099 also offers both down mode and pass-through operation for different applications. In down mode, the output voltage can still be regulated at target value even when input voltage is higher than output voltage. In pass-through mode, the output voltage follows input voltage. The SSP8099 exits down mode and enters into pass-through mode when VIN > VOUT + 0.3V.
The SSP8099 supports true shutdown function when it is disabled, which disconnects the load from the input supply to reduce the current consumption.
The SSP8099 offers both adjustable output voltage version and fixed output voltage versions. It is available in Green WLCSP-1.22×0.83-6B and TDFN-2×2-6AL packages.
SSP8011
The SSP8011 is a low-power single-key touch sensor IC. The operating mode is divided into Normal mode and Low Power mode. Button mode or Switching mode output can be choosed, and the output level mode is optional.
SSP9461
The SSP9461 is a monolithic, step-down, switch-mode converter with a built-in power MOSFET. Current-mode operation provides a fast transient response and eases loop stabilization.
The wide input range(4.5V to 60V) provides high efficiency output of 1.2A current. Low shutdown mode quiescent current of 0.1μA is suitable for battery-powered applications.
Fault state protection includes Cycle by Cycle OCP and thermal shutdown protection.
SSP9459
The SSP9459 is a monolithic, step-down, switch-mode converter with a built-in power MOSFET. It achieves a 0.5A peak-output current over a wide input supply range with excellent load and line regulation. Current-mode operation provides a fast transient response and eases loop stabilization.
The wide input range(4.5V to 60V) provides high efficiency output of 0.5A current, Low shutdown mode quiescent current of 0.1μA is suitable for battery-powered applications.
Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.
SSP9451
The SSP9451 is a high frequency (1.8MHz) step-down switching regulator with integrated internal high-side high voltage power MOSFET. It provides single 0.6A(or less) highly efficient output with current mode control for fast loop response.
The wide input range(4.2V to 40V) accommodates a variety of step-down applications under mobile environment input conditions.Low shutdown mode quiescent current of 1μA is suitable for battery-powered applications.
High efficiency at light load condition is achieved by scaling down the switching frequency to reduce the switching and gate driving losses.The frequency folding technique helps prevent the inductance current from running out of control at startup. Hot shutdown provides reliable, fault tolerant operation.
