MIC2101/02

38V, Synchronous Buck Controllers

Featuring Adaptive On-Time Control

Hyper Speed Control¥ Family

Features

General Description

x Hyper Speed Control architecture enables:

ꢀ High Delta V operation (V_IN= 38V and V_OUT= 1.2V)

ꢀ Any Capacitor¥ stable

The

Micrel

MIC2101/02

are

constant-frequency,

synchronous buck controllers featuring a unique adaptive

ON-time control architecture. The MIC2101/02 operates

over an input supply range from 4.5V to 38V and can be

used to supply up to 15A of output current. The output

voltage is adjustable down to 0.8V with a guaranteed

accuracy of ±1%. The device operates with programmable

switching frequency from 200kHz to 600kHz.

x 4.5V to 38V input voltage

x Adjustable output voltage from 0.8 V to 24V (also limited

by duty cycle)

x 200kHz to 600kHz, programmable switching frequency

x Hyper Light Load Control (MIC2101)

x Hyper Speed Control (MIC2102)

x Enable input and Power Good output

x Built-in 5V regulator for single-supply operation

Micrel’s Hyper Light Load™ architecture provides the same

high-efficiency and ultra-fast transient response as the Hyper

Speed Control architecture under the medium to heavy loads,

but also maintains high efficiency under light load conditions

by transitioning to variable frequency, discontinuous-mode

operation.

x Programmable current limit and fold-back “hiccup” mode

short-circuit protection

The MIC2101/02 offers a full suite of protection features to

ensure protection of the IC during fault conditions. These

include under-voltage lockout to ensure proper operation

under power-sag conditions, internal soft-start to reduce

inrush current, fold-back current limit, “hiccup” mode short-

circuit protection and thermal shutdown.

x 5ms internal soft-start, internal compensation, and

thermal shutdown

x Supports safe start-up into a pre-biased output

x –40qC to +125qC junction temperature range

x Available in 16-pin 3mm x 3mm QFN package

All support documentation can be found on Micrel’s web

site at: www.micrel.com.

Applications

x Distributed power systems

x Networking/telecom Infrastructure

x Printers, scanners, graphic cards, and video cards
