94% 효율을 가진 PFM/PWM 자동변환 전류-모드 DC-DC Boost 변환기

A 94% Efficiency Current-mode DC-DC boost converter with automatic PFM/PWM conversion

초록

This paper presents a high performance DC-DC boost converter by current-mode control method. As load current change, the converter change PWM/PFM operation automatically. current-mode DC-DC boost converter is implemented in a standard 0.35μm CMOS process. The peak efficiency was 94 % with a switching frequency of 1.2MHz.
