- Figure 1. LM317 and HC4053 combine to make a PWM power DAC while Q1 forces preregulator U3 to track and maintain a constant 3 V U2 I/O headroom differential to improve efficiency
- Figure 2. VOUT (1.25 V to 12.5 V) versus PWM D (0 to 1) where VOUT = 1.25 / (1 - 0.9 D)
- Figure 3. The inverse of Figure 2 or, the PWM D required for any given VOUT, where PWM D = (1.111 - 1.389/VOUT)
