MP2116DQ
DESCRIPTION
The MP2116 is an internally pensated 1.25MHz, 2A synchronous step-down switching DC-DC converter plus a standalone low-input
R FEATURES
- 100% Duty Cycle Low Dropout Operation
O (High-Side PFET) F
- 2A Switcher Output Current at VIN=3V voltage, 0.5A low dropout (LDO) linear regulator. It is ideal for powering portable equipment that operates from a single cell Lithium-Ion (Li+)
D Battery. The MP2116 can provide up to 2A to the switcher output, and 0.5A load current to
E the LDO output from a 2.5V to 6V input voltage.
Both output voltages can be regulated as low
D as 0.6V. N S 2 The 2A Synchronous switcher features integrated high-side and low-side switch for
E N 8 high efficiency and small footprint. With peak current mode control and internal pensation,
M IG 1 the MP2116 is stable with ceramic capacitors. 2 Fault condition protection includes cycle-by- cycle current limiting and thermal shutdown.
M S P The standalone low-input voltage 0.5A LDO is used to power noise...
