We caught this guy showing off his bicep on a Siemens PSB2120 power controller integrated circuit. The chip is a ISDN system remote power controller consisting of a pulse width modulator (PWM) circuit designed for fixed-frequency switching regulators especially for telephony and ISDN environments.
The chip containing this artwork was loaned to us by Chipworks, a company that is an international provider of reverse engineering services, analyzing the circuitry and physical composition of semiconductor chips and electronics systems for competitive study, intellectual property support, and reliability assurance.
