MIC2132 operates over an input supply range from 8V to 75V. The output voltage is adjustable down to 0.6V with an ensured accuracy of ±1% at the FBS pin. The device operates with programmable switching frequency from 100 kHz to 1 MHz per phase. The Hyper Speed Control® architecture supports ultrafast transient response under medium to heavy loads. The soft start is also programmable externally with a capacitor, thus enabling safe start-ups into heavy loads. MIC2132 has a remote sense amplifier for accurate output voltage control. MIC2132 offers a full suite of protection features to ensure protection of the IC during Fault conditions. These include undervoltage lockout to ensure proper operation, programmable soft start to reduce inrush current, Hiccup mode short-circuit protection and thermal shutdown. MIC2132 is available in a 32-pin, 5 mm x 5 mm VQFN package with a -40°C to +125°C operating junction temperature range. Package Type EN DH2 PGND SW2 DL2 ILIM CSH AGND *Includes Exposed Thermal Pad (EP); see Table 3-1.
