Output frequency equals oscillator frequency for the x8C43. 5. PSRR of VREF, Error Amp and PWM Comparator combination. NOTES: 1. These parameters, although guaranteed over the recommended operating conditions, are not tested in production. 2. Parameter measured at trip point of latch. 3. Gain ratio is defined as: ∆VCOMP ∆V(ISENSE) TelCom Semiconductor reserves the right to make changes in the circuitry or specifications detailed in this manual at any time without notice. Minimums and maximums are guaranteed. All other specifications are intended as guidelines only. TelCom Semiconductor assumes no responsibility for the use of any circuits described herein and makes no representations that they are free from patent infringement. *Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability.
