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.
H9108
The H9108 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulation.The H9108 requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package .
H9008
The H9008 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makes the H9008 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage. The H9008 requires a minimal number of readily available, external components and is available in a space saving SOT23-5 package.
