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.
