... A disable pad, accessible only on the die, can also be used to disable the driver. An internal circuit shuts down the switching regulator when the lamp drive voltage exceeds 112V peak-to-peak. This conserves power and extends battery life. The IMP525 is available in MicroSO and SO-8 packages and in die form. Block Diagram ...
