SNVS074D – MAY 2001 – REVISED APRIL 2013

Select R1 to be approximately 1 kΩ, use a 1% resistor for best stability.

Component Values shown are for VIN = 20V,

VOUT = 10V, ILOAD = 1A.

CIN: — 470 μF, 35V, Aluminum Electrolytic Nichicon “PM Series”

COUT: — 220 μF, 35V Aluminum Electrolytic, Nichicon “PM Series”

D1 — 2A, 60V Schottky Rectifier, 21DQ06 (International Rectifier)

See INDUCTOR SELECTION PROCEDURE L1 — 100

μH,

R1 — 1 kΩ, 1%

R2 — 7.15k, 1%

CFF — 3.3 nF

Typical Values

CSS—0.1 μF

CDELAY—0.1 μF

RPULL UP — 4.7k (use 22k if VOUT is ≥ 45V)

† Small signal Schottky diode to prevent damage to feedback pin by negative spike when output is shorted (CFF not

being able to discharge immediately will drag feedback pin below ground). Required if VIN > 40V
