ZSPM1025C Datasheet, PDF (11/38 Pages) List of Unclassifed Manufacturers – True Digital PWM Controller (Single-Phase, Single-Rail)

ZSPM1025C / ZSPM1025D
A high-reliability, high-temperature one-time programmable memory (OTP) is used to store configuration param-
eters. All required bias and reference voltages are internally derived from the external supply voltage.
