At present, digitally-controlled DC-DC converters are widely developed because of development time reduction and cost saving than analog controlled method. This paper suggests a high-resolution DPWM Generator for digitally controlled DC-DC converters using low operation frequency. To reduce the operation frequency, proposed method controls the slope of ramp signal using charged current in capacitor. Proposed DPWM Generator was composed with 3bits, 4bits, 5bits shift registers and 3bits Up/Down counter to control the high duty resolution (each duty control rates : 20%, 5%, 1%, 0.125%). The proposed DPWM generator has maximum 200MHz operation frequency for 200kHz∼10MHz switching frequency of dc-dc converter, and it controlled to 0.125% duty rate for high output resolution. For the verification of proposed DPWM Generator, the simulations are carried out with ModelSim based on verilog.
