VO ripple and VSW switching waveform. VIN = 12 V,
VO = 3.3 V and L = 10 µH (IHLP2525EZ type). CO consists
of MLCC of 4.7 µF and tantalum of 100 µF/20 V x 2
VSW: 10 V/div
VO: 1 V/div

IL: 5 A/div
Overcurrent protection at IO = 8 ~ 10 A. VIN = 12 V, VO = 3.3
V and L = 10 µH (IHLP2525EZ type). CO consists of MLCC
of 4.7 µF and tantalum of 100 µF/20 V x 2
IL: 2 A/div
t: 50 µs/div
Transient response. VIN = 12 V, VO = 3.3 V and L = 10 µH
(IHLP2525EZ type). CO consists of MLCC of 4.7 µF and
tantalum of 100 µF/20 V x 2. Output current steps up and
down between 0.4 A and 4 A with less than 1 µs rising and
falling time.
